INTRODUCTION TO BEAD FILTRATION EN

WHAT IS THE THEORY BEHIND BEAD FILTER OPERATION?

Bead lters accomplish two goals, one being water polishing (solids capture) and the other being bio ltration. Other ltration systems also

accomplish these goals, but are much larger and more dicult to clean. The advantage of the bead lter is that it provides a home for

benecial bacteria with high surface area for a large colony per cubic foot and ne particulate straining all within the same vessel. The other

big advantage the bead lters have over other types of lters is that they are much easier to clean. This makes the hobby of KOI or pond

keeping a lot more enjoyable, with less work involved in maintaining a healthy environment for the sh.

HOW DOES A BEAD FILTER PERFORM MECHANICAL FILTRATION?

Mechanical ltration or clarication is the process of removing suspended solids from water. Suspended solids in a recirculating system are

generally small particles of undigested food, bacteria, and algae. These solids tend to reduce the clarifying of water and cause problems in

consuming tremendous amounts of oxygen, also needed by our beloved sh. Bead lters remove solids from water by dierent mechanisms.

Physical straining is probably the most dominant mechanism of removing larger particles (>50 microns). Finer particles (<20 microns) are

removed at a lower rate by a process called bio absorption. The particles are captured by bacterial bio lm on the surface of the bead. Studies

show that bead lters capture 100% of particles >50 microns and 48% of particles in the 5-10 micron range per pass. The more passes the

more solids captured. **Important** in order for the bead lter to perform FINE micron straining it MUST be fully colonized with bacteria.

Depending on the temperature this can take up to 4-6 weeks, at temps. above 60-65 degrees F.

HOW DOES A BEAD FILTER PERFORM BIO FILTRATION?

Bio ltration depends on the establishment of a colony of bacteria on the surface of the beads large enough to convert dissolved toxic

nitrogenous waste to harmless compounds. When the bacteria are given the proper environment, they grow in a thin bio lm on the surface

of each bead. Each cubic foot of beads contains about 600,000 beads. This is one of the secrets of the bead lters´ success--high surface area

per cubic foot for a large bacterial colony per cubic foot of lter media. The two most common types of bacteria are, Nitrosamines, which is

responsible for the break down of ammonia in the system. The next is Nitrobacteria, which is responsible for the breakdown of nitrite into

relatively harmless nitrate. **Important** in order for the bead lter to perform Bio ltration the beads must be colonized with a large

enough colony to handle the load of dissolved ammonia presented to it. This may take up to 4-6 weeks at temps. above 60-65 degrees F. Until

the colony has grown large enough, the pond owner MUST be responsible for monitoring the levels of ammonia and nitrites in the pond

water and taking appropriate measures to correct dangerously high levels.

HOW DO YOU SIZE A BEADFILTER?

Unlike the most of the traditional multi-chamber lters we do not only regard pond capacity but also to the (future) sh load. One often

forgets to keep in mind that our koi grow very fast each year and we often buy new sh. In case of a multi-chamber lter this means we need

a lot of extra space to install the lter but in the case of an Xclear Beadlter the dierence in dimensions is not that big. What matters is the

amount of beads. The biggest model can be placed on a surface of 1m² ! So rst check the max. sh load for each model that suits your

(future) sh load. For ornamental ponds without koi you can multiply the max. pond content by 2.

WHAT PUMP DO IUSE WITH MY FILTER?

As Xclear Beadlters are pressure vessels, the pump sits in front of the lter, therefore almost any external dry mounted pump with a head

pressure of 6-7 is suitable. Keep the pressure loss in mind regarding the lter and the pipe work. A good rule of thumb is that the pump must

be capable to have a ow of about 40 - 50% of the pond contents per hour with a head pressure of 0,2 – 0,3 bar (2 - 3 meter). With the bypass

system it is also possible to use low pressure pumps which saves a lot of energy!

IS AN XCLEAR BEADFILTER ONLY SUITABLE FOR PONDS?

No, an Xclear Beadlter is also very suitable for salt- and fresh water aquaria and

is also very suitable for swimming ponds.

BYPASS SYSTEM

Installing the bypass allows the use of more economical pumps. Due to a very compact

bypass-system, the multi-way valve is completely unused during ltering as the water

ows directly into the lter and also leaves the lter in a direct line. This action results

in at least 30% less pressure loss (depending on the type of pump). Thanks to its threaded

coupling the bypass system is easy to install. Connection: 400/500/600; 50mm.

750/900; 63mm.

SUGGESTED INSTALLATION OF AN XCLEAR BEADFILTER

A swing check valve installed below water level in a location of easy access makes the pump prime much more easily and prevents the pump

from being blown empty during rinse with blower.

PRE-FILTERS

The in- and output system of a beadlter has laterals (slotted pipe) to keep the beads inside the lter and therefore we need a pre-lter to

prevent the possibility of large solids (string algae, pine needles, leaves and sh waste) coming in from a bottom drain or submersible pump.

We strongly recommend the use of a pre-lter in the above-described situations.

There are several options that can be used as a pre-lter; by example you can use the Xclear Sieve (a gravity fed sieve lter) that can keep out

the larger solids.

SETTING UP YOUR XCLEAR BEADFILTER

1. Xclear Beadlter 400/500/600: Attach the ball valve part with the blue handle (1) to the union part at the bottom of the lter (close the

valve). Make sure the rubber o-ring is in place. 750/900: fasten the complete valve part into the female threaded hole in the bottom of the

lter. Make sure the rubber o-ring is in place to seal this part.

2. Fill the tank about one half full of water. Now pour the beads into the tank from the top opening.

3. Install the air relief valve as on the picture above. Remove the black plug from the multiport valve (see picture) and install the pressure

gauge in the multiport valve with Teon tape or Loctite 5331 to make it waterproof.

4. Put the big O-ring in the cut-away of the top opening. Put the cap on the opening. First use a stainless steel washer before you use the

stainless steel bolts. Gradually fasten the bolts one by one, so do not completely fasten one bolt at once.

5. Attach the multiport valve (rst put the O-rings in place according the above displayed photos). Be sure that the “O” rings of the valve are

properly positioned. ** Important ** Hand tighten the unions, do not use a wrench, as you may crack the outer ring by over tightening.

Insert the blower with the section of PVC pipe that came with the lter into the upper union of spring check valve for the blower

attachment (Do Not Glue). Don’t pick up the blower on the silencer side (top cap) as it is not glued to the blower. When you turn on the

blower, the spring check valve will open allowing pressurized air to enter the lter tank for bead agitation.

6. Make pipe connections on the female threaded sides. The pressure (pump) line, return line, and the waste line connections are clearly

labelled on the valve. ** Important ** Install a swing check valve on the suction line from the pond to the pump. Install this below water

level and you will have much less trouble priming your pump. See ideal installation diagram at the front of the manual. Also be sure that

the waste water is directed away from the lter site, so that there is not settling of the lter system from moist ground around the lter.

7. First put the multiport valve to the WASTE position before you start ltering to clean the pipework and the lter from small plastic parts

like bead and/or PVC “dust”. Start the pump and keep it running until the water is clear of waste. Stop the pump, put the valve to the

FILTER position and start the pump again. You are now ltering!

TIP: Use 3/3 PVC unions 1½” or 2” male thread with rubber ring (see photo) for the pipe connections. With

these unions the connections on the multiport valve are waterproof without the use of glue or kit, and it

allows the valve to be easily dismantled. The Xclear Beadlter 400/500/600 have an 1½” connection, the

Xclear Beadlter 750/900 have a 2” connection.

1. 400/500/600: Schroef het kraangedeelte met de blauwe hendel (1) van de afvoerkraan vast aan de wartel zoals op de foto (kraan

dichtzetten). Let er op dat de rubberen o-ring goed zit. 750/900: schroef het complete kraangedeelte onder in het vat. Let op dat de

platte rubber ring goed afsluit tussen het vat en de draadfitting.

2. Giet de beads vanuit de plastic zakken in de grote opening, boven in het filter.

3. Bij het deksel wordt een ontluchtingskraantje geleverd. Draai het ontluchtingskraantje in het deksel volgens bovenstaande foto.

Schroef het zwarte afsluitplugje met o-ring uit de 6-wegventiel en schroef de manometer met wat teflon tape of Loctite 5331 in de

6-weg ventiel zoals op bovenstaande foto.

4. Leg de grote O-ring in de uitsparing rondom de opening. Leg het deksel op het filter. Gebruik eerst een RVS ring en dan de RVS

bouten. Draai alle bouten om de beurt geleidelijk aan, niet per stuk in één keer geheel indraaien.

5. Monteer de 6-weg klep door de 2 schroefkoppelingen goed aan te draaien op de filterbehuizing (eerst O-ringen plaatsen zoals op

bovenstaande foto’s). Op de 6-wegklep is al een transparante terugslagklep voor de blower gemonteerd. Hierop kunt u de blower

met de witte pvc buis in zetten (niet lijmen, alleen klemmen!).

6. Op de 6-weg klep staat vermeld waar de aansluitstukken gemonteerd moeten worden: PUMP (pompaansluiting) RETURN (terug

naar de vijver), WASTE (afvoer naar riool). Deze 3 aansluitingen hebben een binnendraad aansluiting waarop u de betreffende

koppelstukken kunt aansluiten. Wij adviseren u om aan de WASTE aansluiting een kijkglas of een stukje transparante pvc buis te

monteren zodat u kunt zien wanneer het spoelproces klaar is.

7. Wanneer alles goed is aangesloten zet u de klep eerst op “WASTE” en start u de pomp om eventuele kleine plastic vuildeeltjes van

de beads in het filter af te voeren voordat u gaat filteren. Wanneer er geen vuil meer uit het filter komt stopt u de pomp, zet u de

klep op FILTER en zet u de pomp weer aan.

TIP:

Gebruik voor het aansluiten van de pomp, retour en de afvoer 3/3 PVC koppelingen met 1½” of 2”

buitendraad met rubber ring x 50mmm lijmverbinding (zie foto hiernaast). Met deze koppelingen zijn

uw verbindingen op de 6-wegklep waterdicht zonder het gebruik van lijm of kit en kan de 6-wegklep

altijd nog eenvoudig worden losgekoppeld.

De 400/500/600 hebben een 1½” aansluiting, de 750/900 hebben een 2” aansluiting.

XCLEAR BEADFILTER OPERATION

Water enters into the tank (A) under pressure from the pump.

The solids collect in the centre of the lter, waiting to be hydraulically

purged out under pressure from the pump. All you have to do is open

the sludge separation valve (B) with the pump running and the lter

in its normal ltration mode. The heavier solids are evacuated in just

a couple of seconds. What does all of this mean? The most unique,

ecient lter of its kind. An ecient lter doesn’t hold solids, it gets

rid of them!

Now that the water is in the tank it is forced slowly upward in the

vessel through millions of beads about 2-3mm in size. On these beads

there are billions of nitrifying bacteria and these hungry bacteria are

consuming vast amounts of ammonia, nitrites, etc. and performing

what is known as nitrication. This is how we actually get clean and

healthy water due to the work these minute organisms are

performing. Water continues to ow upward through the beads and

exits out of the vessel via the top spray bar (C). This water then

continues into the multi port valve and depending on the setting on

the multi port (FILTER), the water goes on to the pond.

The Xclear Beadlter series have another unique feature: the Blower

(D). This blower is mounted on a special air check valve. It is

important that the valve is in the rinse position for the blower

gitation of the beads. When the blower is active the beads and debris are dispersed throughout the interior of the lter. This breaks up the

beads and releases the trapped particles. This debris then can easily be backwashed out to waste through the spray bar (C). After the RINSE

cycle with air we perform a backwash in which the water enters at C and leaves the lter through A. After the backwash there will be another

RINSE cycle but with water instead of air. This takes any remaining debris and sends it to waste (from Ato C), instead of sending a cloud of

dirt back to the pond.

THE MULTIPORT VALVE

“FILTER”: Water enters the Beadlter at (A) and goes upward through the beads and exits out of the vessel via the top spray bar (C) to return

to the pond.

“RECIRCULATE”: With the “RECIRCULATE” feature you can bypass your lter and ow the water from pond to pump to multiport and back to

pond. This comes in handy when you are treating the pond.

“WASTE”: Allows the water to bypass the lter and go directly to waste, such as when you are performing a backwash cycle. You can also use

the waste setting to vacuum out your pond without the garbage going into your lter, it bypasses the lter via the multiport and goes out to

waste.

“RINSE”: The rst time we use the RINSE feature to wash the beads with the blower which forces huge amounts of air into the vessel and

since air rises in water, the beads are broken apart by this action, making a thorough backwash easy to accomplish. After the backwash

function we use the RINSE feature again but now with water instead of air. It is impossible to get every little bit of debris out of a lter and

this causes these minute particles to exit in the waste line instead of going back into the pond.

“BACKWASH”: In this position we let the pump run until the water in sight glass is clear (normally 1 to 2 minutes). The water enters the lter

from the top spray bar (C) exits the vessel at (A) and goes out to waste.

“CLOSED”: Valve closed. Never use this position with the pump running.

BACKWASH INSTRUCTIONS

When you rst start up your lter, we recommend that you let it run

for two weeks before you perform your rst backwash. After that, 2

-3 times a week during the warm season should be all that is needed.

During the winter months backwashing can be reduced to as little as

once every 2-3 weeks. To perform a backwash do the following:

1. With the pump running open the valve to the sludge drain (B).

Keep it open for 15-20 seconds, then shut it. This will purge the

large solids that have made it into the lter and settled out in the

bottom of the tank to waste. It is very important to get them out of

the system for overall water quality and more ecient lter

operation.

2. Next turn o the pump.

3. Move the multiport valve to the rinse position. When the blower

(D) is activated in this position, air and a small amount of water will

leave the lter to waste. It is important that the valve is in the

rinse position for the blower agitation of the beads.

4. Activate the blower unit for 1-2 minutes. During this time the

beads and debris are dispersed throughout the interior of the lter.

This breaks up the beads and releases the trapped particles. This

debris then can easily be backwashed out to waste. Place your ear

to the side of the tank. You should hear a lot of “plopping and

sloshing” going on inside the lter. If you only hear air moving

through the lter then you need to open the tank and make sure that the beads are not gelled.

5. !!IMPORTANT!! Some water has been forced out of the lter. The tank needs to be entirely full of water before backwash is performed. To

ll the tank with water, open the air release valve at the top of the lter and turn on the pump. When water sprays out the air release valve,

the tank is full. Turn o the pump and shut the air release valve.

6. Move the valve to the backwash position. Turn on the pump and run until the water is clear in the sight glass. The water will run clear at

rst then dark and then clear.

7. Move the multiport valve to the rinse position. Turn on the pump and run until water is clear in the sight glass. This takes any remaining

debris and sends it to waste, instead of sending a cloud of dirt back to the pond. Turn o the pump.

8. Move the multiport valve to the lter position and turn on the pump. Backwash is done.

*Note* The backwash instructions on the label of the blower are a short version of the above instructions.

WATER SAVING DRAIN:The Xclear Beadlters 400/500/600 come standard with a water saving sludge drain. The water saving sludge drain

allows a low volume backwash if water is in short supply, expensive, or you have a low volume pond, but heavily stocked. After using the

Blower or an initial hydraulic backwash to break up the bead pack, let the heavy solids settle in the water below the bead pack then open the

sludge drain and drain them to waste. The sludge drain will allow the entire tank to be drained, without losing beads through the sludge

drain. So one is only using the water volume of the lter tank to wash the beads. This saves many gallons of water that may be used with an

hydraulic backwash. This is only valid for the Xclear Beadlters 400/500/600, not for the Xclear Beadlters 750/900! The 750 and

900 do not have a valve outlet with strainer which causes the beads to come out of the lter. Keep close attention when the beads start

coming out of the lter and close it.

NOTE: The “normal” backwash procedure costs more water, but by relling your pond after backwash you will make, necessary water

changes automatically! Water changes of 5 to 10% per week is a good rule of thumb for most ponds.

FILTER MATURATION

This has been stated earlier, but is very important. It takes 4-6 weeks of operation at temperatures above 60-65 degrees F (16-18°C). Before

there is a large enough colony of bacteria to handle the bioconversion of ammonia and ne particulate straining. During this transition period

the pond owner must watch the ammonia and nitrite levels in the pond. If they become dangerously high, steps should be taken to correct

the problem, such as a water change. Also during this period ne particulate straining will not be fully mature and you may notice your water

being less polished than you would like it to be. Both of the above issues will improve with time and the growth of the bacterial colony. This

will occur with any type of bead lter used. To help the nitrication process you can add bacterial cultures.

ULTRAVIOLET LIGHT STERILIZERS

Bead lters will remove suspended particles down to 5-10 microns in size. However, some algae particles are smaller than 5 microns and will

not be removed by the beads. These tiny algae cells will give the water a green cast and aect the clarity of the water. If the pond owner

wants crystal clear swimming pool clarity, then a UV-light is needed. Uv-lights will also remove many harmful bacteria and decrease the

suspended bacterial counts in the water. We recommend the use of uv-lights for the above reasons.

*Note* If you leave your lter not backwashed for two or more weeks, it is a good idea to do an extra long blower treatment on the beads.

*Word of Caution* If you leave your lter not backwashed for extended periods of time, and you live in an area with relatively soft water,

you may want to buer your pond water. The bacteria in the lter can consume enough alkalinity (KH) in the water to cause a dangerous pH

drop. Total alkalinity should be kept above 50ppm (3° dH) to avoid potentially dangerous shifts. To increase alkalinity, add sodium

bicarbonate, change the water, or add a commercially prepared pH Buers.

NOTES ON NITRIFICATION

When ammonia removal is desired rst start with Pond Support Maintenance bacteria to reduce the organic waste in the pond as high levels

of BOD can inhibit nitrication by competing with the nitrifying micro organisms for necessary oxygen. After applying Pond Support

Maintenance wait 24 to 48 hours to do its job, and then apply Pond Support Nitrifying bacteria to start and maintain nitrication. Check to

make sure that the pond pH is in the correct range for nitrication. Adjust the pond pH to a range of 7.5 to 8.7, and check if adequate alkalinity

is present as you must maintain a level of at least 50/ppm (3° dH) of alkalinity at all times. This is necessary as nitrifying micro organisms use

7.1 lbs of alkalinity for each pound of ammonia removed (oxidized). If proper alkalinity is not present, nitrication will not occur, and if

alkalinity is lost, nitrication will cease and the pond pH will drop due to the nitrifying cultures activity. To increase alkalinity add pH buer

or Pond Support KH+ until you achieve an alkalinity level of 50/ppm (3° dH) to 100/ppm (5,6° dH) (minimum), and then maintain the

alkalinity at a level of at least 50/ppm (3° dH).

INTERNAL INSPECTION

We recommend that twice a season you inspect the output

laterals.

1. Backwash your lter then turn o the pump and leave the valve

in the backwash position. Also open the drain plug at base of

the lter.

2. Open the air release valve at the top of the lter. You will notice

air rushing into the lter. This represents water draining out of

the lter. CAUTION! The Xclear Beadlters 750/900 do not have

a valve outlet with strainer which causes the beads to come out

of the lter. Keep close attention when the beads start coming

out of the lter and close it.

3. When air stops being sucked into the lter, most of the water

has drained out of the lter. Remove the cap.

4. Now inspect the beads. Do they look clean after the backwash?

Are there areas of caked beads? If you nd areas of dirty beads

or caked beads, you may need to adjust the span of time that

you use the blower, or increase the backwash time, or possibly

the backwashing frequency. If you nd caked beads, now is the

time to break them apart. Using your hand or a stick, stir the

beads and break up any clumps that you might nd.

5. Wipe any beads stuck to the output laterals o and inspect

them. Make sure that they clear of any obstructions. If there is

material inside the laterals, use a high pressure cleaner to make

the laterals clean.

6. Next, inspect the backwash laterals. They will need to be removed. This can be done by reaching down in the lter and unscrewing the

union that holds the backwash lateral in place (you may have to remove a greater part of the beads). When loose inspect them for debris.

Clean if needed then replace when done.

7. Replace the top cap and make sure that it is secure. Pay attention to the position of the air release valve so that it is pointed in the direction

you wish.

8. When the top cap is back on, with the air release valve open, move the lter valve to the Filter position and turn on the pump. When water

comes out of the air release valve, close the valve and perform another backwash and rinse cycle before going back to ltration. Now your

done.

MEDICATING YOUR POND

Sometime during your career as a pond keeper you may need to medicate your pond with chemicals that will

harm the bacterial colonies on the lter media. To insure that they are not damaged follow these simple steps:

1. Do a good backwash on the lter then turn o the pump.

2. Move the valve to the “recirculate position”. This will cause the water to bypass the lter while you are treating your pond. Turn your

pump on.

3. Open the sludge drain at the bottom of the lter and then the air release valve at the top of the lter. Water will start draining out of the

lter without loss of any beads (Xclear Beadlter 400/500/600). CAUTION!The Xclear Beadlter 750/900 do not have a valve outlet with

strainer which causes the beads to come out of the lter. Keep close attention when the beads start coming out of the lter and close it.

Then open the valve a little so only water can come out and no beads. The bead pack will now be surrounded with air instead of water. This

will prevent any bacterial loss from lack of oxygen. The beads will stay moist for several days.

4. When the medication period is over, close the sludge drain, but leave the air release valve open. Turn o the pump and move the handle to

the lter position. Now turn on the pump. You will notice air “whistling” out of the air release valve as the tank rells with water. When

water sprays out of the air release valve turn o the pump. Do a quick backwash and rinse, then go to lter mode.

*Note* Depending on the chemicals used, it is advisable to do a 50% water change before starting the lter back

up. Check with your dealer.

WINTERIZING YOUR FILTER

It is best for all biological lters to operate 24/7.

Sludgedrain

If you live in an area where you experience hard freezing, you may decide to shut your lter down for the winter. Do the

following:

1. Do a good backwash of the lter. Move the multiport valve to the “winter” position (between CLOSED and WASTE).

2. Turn o your pump and open the drain plugs on the pump strainer basket.

3. Open the drain plug at the base of the main lter and then the air release valve at the top of the lter. Water will drain out of the lter, but

no beads will be lost (Xclear Beadlter 400/500/600). CAUTION!The Xclear Beadlter 750/900 do not have a valve outlet with strainer

which causes the beads to come out of the lter. Keep close attention when the beads start coming out of the lter and close it. Then open

the valve a little bit so only water can come out and no beads.

4. Loosen all connections and drain exposed pipes, so that no water will be trapped. This is especially important for your UV lights!

In the spring:

1. Tighten all the connections that you loosened in the fall.

2. Move the multiport valve to the lter position and open the air release valve at the top of the lter and close the drain plug. Turn on the

pump. When water comes out of the air release valve at the top of the lter, shut it and turn o the pump. Now do a good backwash and

rinse before going to the lter mode. Back up to full capacity. During the rst few weeks of operation in the spring, it is a good idea for the

pond owner to do frequent checks of the ammonia and nitrite levels.

TROUBLE SHOOTING

DECREASE IN WATER FLOW

1. If you notice that your water ow is decreasing the most likely cause is that the lter needs to be backwashed. The bead lter is designed

to trap solids and does it very well. When fully loaded with solids, the lter may restrict ow. Perform a backwash and rinse.

2. If after backwashing the lter the water ow is still low, next check the strainer basket on the pump. Be sure that it is clean and replace.

3. If the ow is still low after cleaning your pre-lter and there was plenty of ow through the pump, then you need to inspect the internals

of the lter. Check to see if the laterals are clear of obstruction and that the beads are not caked into large clumps. When the bead pack

gets “gelled” they are hard to break apart with backwashing and doing a blower treatment. They may need to be manually broken apart.

When the beads are gelled they tend to cause “Channelling,” which means that the bead pack is totally clogged and water will follow

paths of little resistance through or around the bead pack. When Channelling is occurring you will notice that after backwashing the lter

quickly clogs and ow slows in intervals that used to take 1-2 weeks, now ow slows in 2-3 days. Follow the directions in the internal

inspection section of the lter operation section of the manual.

4. If you follow the above steps and your ow is still low, PLEASE call your dealer.

TROUBLE SHOOTING DECREASE IN WATER CLARITY

1. If your lter has a mature bacterial colony, which could take up to 4-6 weeks at temps. above 60-65 degrees F. (15-22º C), and your water

quality and clarity have been good then decrease, the rst thing to do is a good backwash and rinse. Spend an extra amount of time with

the blower agitation of the beads.

2. If your clarity does not improve or improves then decreases quickly, open the lter and inspect the internal condition of the laterals and

the beads. If the beads are gelled and channelling is occurring, then the water will bypass most of the bead pack and no mechanical

ltration will occur. Manually break up the beads and make sure the laterals are clear of obstruction.

3. If your water clarity does not improve, and you have UV-lights on the system, check to see if the bulbs are still working. Depending on the

bulb, some UV-light bulbs will only have killing power for six months of continuous run. Others will last for a year or longer. Check to see

when they were last changed and replace if needed. They should be changed at least once a season.

4. If your clarity does not improve, check the water ow out of the system. The entire pond water volume should be turned over through the

lter system at least 3-4 times per day. If turn over time is slow then the amount of solids that the lter can capture will decrease. Check to

make sure that there are no ow restrictions. Follow the low ow trouble-shooting chart. Also make sure that your pump is large enough

to move the amount of water needed for enough turn overs through the lter.

5. If after following the above suggestions and the clarity has not improved, PLEASE call your dealer.

HIGH AMMONIA AND NITRITE WITH PREVIOUSLY STABLE STATE

If your pond has been up and running at warm temperatures (60-70 F or +/- 20º C) for six or more weeks and your ammonia and nitrite levels

have been previously controlled, but you experience a spike in the ammonia level try the following:

1. Perform an extra long blower treatment on the bead pack and an extra long backwash. If the bead pack becomes totally clogged with

solids, the available surface area for bioconversion drops signicantly. Backwashing will open up the active surface area and bioconversion

will resume.

2. If after backwashing the ammonia levels are still high, open the lter. Check the laterals to make sure they are clear, stir the beads to break

up any gelled areas and then backwash.

3. If ammonia levels are still high, consider how much food is being fed to the sh. One cubic foot of mature beads can handle around one

pound of 35% protein food per day. Check to see how many cubic feet of beads are in your lter and compare that with the amount of food

you are feeding.

4. If ammonia levels are still high, check the ow rate through the lter. The entire volume of the pond should be turned over through the

lter AT LEAST 3-4 times per day. If the ow is down for some reason, bioconversion of ammonia will also slow. If you nd the ow is in fact

down, follow the troubleshooting ow chart for correcting low ows.

5. If all the above are found to be in good condition, consider the sh load on the pond. This actually also relates to the above discussion

about amount of food fed. If you have a heavily stocked pond you will also be feeding more to the sh and thus adding more nitrogen to

the pond water that will have to be bio converted. Again, consider your lter size and what you are asking it to do.

6. If the ammonia levels are still high, call your dealer.

All models have a multi-port valve and a powerful blower.

ALGEMENE INFO OVER BEADFILTERS NL

Beadlters zijn gesloten (druk)vaten gevuld met duizenden plastic korreltjes (beads). Omdat deze korreltjes drijven zorgen ze voor de

mechanische ltratie en vanwege hun grote aanhechtingsoppervlak dienen ze ook als biologische ltratie.

Mechanische ltratie: de korrels drijven in een gesloten vat en zitten daardoor heel erg dicht op elkaar. Het water wordt er door de druk

van de pomp doorheen geleid waardoor de vuildeeltjes in deze korrels blijven hangen. Naarmate het lter langere tijd wordt gebruikt wordt

ook de biolm (een plakkerige laag) om de korrels dikker waardoor er steeds jner vuil wordt opgevangen.

Biologische ltratie: de plastic korrels hebben een aanhechtingsoppervlakte van zo’n 1600m² (6 x zo veel als bijvoorbeeld een blauwe

Japanse mat). De biolmlaag om de korrels biedt dus gigantisch veel oppervlakte voor de bacteriën die ammonium en nitriet afbreken.

WELK MODEL XCLEAR BEADFILTER IS GESCHIKT VOOR MIJN VIJVER?

In tegenstelling tot de meeste traditionele meerkamerltersystemen kijken we bij de Xclear beadlter niet alleen naar de vijverinhoud, maar

eerder naar de (toekomstige) visbezetting. Vaak wordt er te weinig rekening gehouden met het feit dat koi jaarlijks ink groeien en dat er

regelmatig nog eens een visje bijgekocht wordt. Bij meerkamersystemen houdt dat vaak in dat er een inke ruimte gereserveerd zal moeten

worden om het lter te kunnen installeren terwijl het verschil in omvang bij de Xclear Beadlter niet zo heel veel scheelt per model, het gaat

hier vooral om de hoeveelheid ltermateriaal (beads). Het grootste model neemt nog geen 1m² plaats in beslag! Kijk daarom eerst in de tabel

van de modellen welke (toekomstige!) visbezetting bij uw vijver past en ga daarna naar de vijverinhoud kijken. Voor siervijvers zonder koi

kunt u in de tabel de vijverinhoud maal twee hanteren.

WAT VOOR POMP KAN IK GEBRUIKEN VOOR EEN XCLEAR BEADFILTER?

Aangezien de Xclear beadlters druklters zijn moet de pomp voor het lter worden geplaatst. Meestal zijn dit zwembadpompen maar

bepaalde vijverpompen met tenminste 6-7 meter opvoerhoogte zijn ook geschikt. Houd wel rekening met het drukverlies dat het lter en de

leidingen met zich meebrengen. Bij het gebruik van het Beadlter Bypass systeem is het mogelijk om pompen met lagere druk te gebruiken

wat een grote besparing in de stroomkosten met zich meebrengt.

KAN IK EEN XCLEAR BEADFILTER ALLEEN VOOR VIJVERS GEBRUIKEN?

Nee, een Beadlter is tevens uitermate geschikt voor zee- en zoetwateraquaria en zwemvijvers.

BEADFILTER BYPASS SYSTEEM

Met het Bypass systeem wordt het gebruik van

energiezuinige pompen mogelijk. Dankzij een

zeer compact bypass systeem wordt de

zeswegklep tijdens het lteren volledig omzeild

en gaat het water in een rechte lijn direct het

lter in en uit. Dit zorgt voor minimaal 30%

minder drukverlies (afhankelijk van het type

pomp). Het bypass systeem is dankzij de

schroefkoppelingen zeer eenvoudig te monteren.

Aansluitingen: Bypass 400-500-600; 50mm.

Bypass 750-900; 63mm.

VOORBEELD INSTALLATIE VAN EEN XCLEAR BEADFILTER

Een terugslagklep onder het waterniveau tussen het lter en de pomp zorgt ervoor dat de pomp gemakkelijk kan aanzuigen en niet wordt

leeggeblazen door de blower tijdens het spoelen.

VOORFILTERS

Omdat het in- en uitlaatsysteem van een beadlter een zeer kleine doorlaat heeft kan een beadlter niet rechtstreeks op de bodemafvoer of

vijverpomp worden aangesloten vanwege de kans op verstopping door draadalgen, (afgestorven) bladeren en ander grof mechanisch vuil.

Gebruik in deze situaties dan ook altijd een voorlter om dit vuil op te vangen.

Als VOORFILTER zijn er meerdere opties aanwezig, zoals de Xclear zwaartekracht gevoede zeefbochtlter.

UW XCLEAR BEADFILTER INSTALLEREN

1. 400/500/600: Schroef het kraangedeelte met de blauwe hendel (1) van de afvoerkraan vast aan de wartel zoals op de foto (kraan

dichtzetten). Let er op dat de rubberen o-ring goed zit. 750/900: schroef het complete kraangedeelte onder in het vat. Let op dat de platte

rubber ring goed afsluit tussen het vat en de draadtting.

2. Giet de beads vanuit de plastic zakken in de grote opening, boven in het lter.

3. Bij het deksel wordt een ontluchtingskraantje geleverd. Draai het ontluchtingskraantje in het deksel volgens bovenstaande foto. Schroef

het zwarte afsluitplugje met o-ring uit de 6-wegventiel en schroef de manometer met wat teon tape of Loctite 5331 in de 6-weg ventiel

zoals op bovenstaande foto.

4. Leg de grote O-ring in de uitsparing rondom de opening. Leg het deksel op het lter. Gebruik eerst een RVS ring en dan de RVS bouten.

Draai alle bouten om de beurt geleidelijk aan, niet per stuk in één keer geheel indraaien.

5. Monteer de 6-weg klep door de 2 schroefkoppelingen goed aan te draaien op de lterbehuizing (eerst O-ringen plaatsen zoals op

bovenstaande foto’s). Op de 6-wegklep is al een transparante terugslagklep voor de blower gemonteerd. Hierop kunt u de blower met de

witte pvc buis in zetten (niet lijmen, alleen klemmen!).

6. Op de 6-weg klep staat vermeld waar de aansluitstukken gemonteerd moeten worden: PUMP (pompaansluiting) RETURN (terug naar de

vijver), WASTE (afvoer naar riool). Deze 3 aansluitingen hebben een binnendraad aansluiting waarop u de betreende koppelstukken kunt

aansluiten. Wij adviseren u om aan de WASTE aansluiting een kijkglas of een stukje transparante pvc buis te monteren zodat u kunt zien

wanneer het spoelproces klaar is.

7. Wanneer alles goed is aangesloten zet u de klep eerst op “WASTE” en start u de pomp om eventuele kleine plastic vuildeeltjes van de

beads in het lter af te voeren voordat u gaat lteren. Wanneer er geen vuil meer uit het lter komt stopt u de pomp, zet u de klep op

FILTER en zet u de pomp weer aan.

TIP:

Gebruik voor het aansluiten van de pomp, retour en de afvoer 3/3 PVC koppelingen met 1½” of 2”

buitendraad met rubber ring x 50mm lijmverbinding (zie foto hiernaast). Met deze koppelingen zijn uw

verbindingen op de 6-wegklep waterdicht zonder het gebruik van lijm of kit en kan de 6-wegklep altijd nog

eenvoudig worden losgekoppeld. De 400/500/600 hebben een 1½” aansluiting, de 750/900 hebben een 2”

aansluiting.
