INTRODUCTION
We at Aqua Ultraviolet would like to take the time to thank you for purchasing the finest filtration system on the market.
For over twenty years, Aqua Ultraviolet has manufactured filtration systems which are in use in many different fields
and industries such as aquariums, aquaculture, public and commercial aquariums, educational institutions, government
agencies, commercial and research organizations throughout the world.
Aqua Ultraviolet Ultima II Filters were created with our customers comfort in mind. Our patented backwash system takes
just a few minutes a week and does not require draining a sludge valve or opening a filter. Within a few short weeks
your filters bacterial bed will be fully established, and with our scientifically designed media you can be assured it will be
well protected. So sit back and enjoy your pond again, courtesy of Aqua Ultraviolet.
HOW FILTRATION WORKS
Biological and mechanical filtration are essential to every pond, without it ammonia from the accumulated fish waste
would harm your fish. The bacterial bed that builds on filter media will nitrify any ammonia in your pond making it a
healthier environment for your aquatic life. Mechanical filtration picks up any debris in the pond, keeping your pond
healthier and your fish happier.
HOW ULTIMA II BIO-MECHANICAL FILTRATION EXCELS
Bio-Mechanical filtration depends on the establishment of a colony of bacteria on the surface of the media that converts
dissolved toxic nitrogenous waste to harmless compounds. When the bacteria are given the proper environment, they
grow in a thin biofilm on the surface of each piece of media. The larger the surface area, the larger the bacterial colony.
Our media surpasses the competition in this area with four to seven times the surface area of any other media available.
In order for the Ultima II filter to perform Bio-Mechanical Filtration the media must first establish itself enough to handle
the load of dissolved ammonia presented to it. Depending on the temperature this can take 2-4 weeks for your filter to
establish itself in your pond environment (this varies depending on climate, weather conditions, fish load and feed rates).
Until the colony has grown large enough, the pond owner MUST be responsible for monitoring the levels of ammonia
and nitrates in the pond water and take the appropriate measures to correct dangerously high levels.
CAUTION: READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION OR OPERATION.
The following instructions should answer most of the questions that you may have about the installation, operation and
use of your new Aqua Ultraviolet Ultima II Filter. If for some reason you should need technical support, we offer this
service for free by telephone [phone], or by fax [phone] M-F 8:00 am - 4:30 pm Pacific Standard time
except selected holidays or you may reach us through the web at www.aquaultraviolet.com.

FREQUENTLY ASKED QUESTIONS
Do I need to add any additional bacteria to my pond or my filter?
No, your Ultima II filter comes pre-seeded with natural bacteria to help the filter establish itself.
Do I need to add additional biological or mechanical filtration to my pond?
Not unless your pond has a lot of large debris (i.e. leaves, pine needles, string algae). If you have large debris in your
pond a leaf basket or other pre-filtration system is recommended.
Can I bury my filter?
Yes, you can bury the filter up to the valve head. Please keep in mind that if you need to drain your filter for winter the
drain valve will be buried and other means may be necessary to drain the filter.
How often do I have to Backwash?
It is recommended to backwash your filter once a week, however, depending on your fish load and feed rate it may be
necessary to backwash more often, or less often. After a few weeks you will begin to notice how often it is necessary for
your own pond.
How often do I have to replace the media?
Never, the media does not have to be replaced.
How often do I need to drain out the sludge?
Never, due to the exceptional backwashing system exclusive to our filters, all the waste is expelled through the waste
line, and thoroughly cleans the filter eliminating the need for a sludge valve.
Can I medicate while the filter is running?
No, due to the non-specific nature of most medications on the market any medication designed to eliminate harmful bac-
teria in your pond would also destroy any beneficial bacteria inside your filter. If you need to medicate for any reason,
you may set the valve to recirculate which will bypass the filter entirely and run through the valve only.
What is the maximum flow rate through my filter?
75 GPM on 1-1/2" Models and 125 GPM on 2" Models.
What size pump should I use?
Your pump will need to be an external direct drive pump that can pump the volume of your pond within one and a half
hours at ten feet of head pressure.
What's the flow loss through the filter?
The filter flow loss ranges from 3-8ft of head, depending on how dirty the filter is.
Do I need to oversize my filter?
No, our filters were designed to handle heavy fish loads and heavy feed rates.
Do I need a pre-filter?
In situations where heavy waste like pine needles, large leaves, etc. are present a pre-filter is recommended.
Do I need to run my filter 24 hours a day?
Yes, the filter converts ammonia from fish waste into harmless compounds creating a safe environment for your fish.

CAUTION: The filter should be installed not more than 6 feet above pond water level, on a level surface, very
firm ground, or equivalent, as recommended by your dealer. Position the filter so that the piping connections,
and unions, control valve, and winter drain are convenient and accessible for operation, service and winterizing
(if needed).
NOTE: For Ultima II 4000 models and up, pour the media inside the filter, which is loaded through the top opening of the
filter.
NOTE: For 1000 and 2000 Filters skip to plumbing the filter, these filters come with media inside.
1. Installing The Media
A. Cap internal standpipe with plastic cap to prevent media from entering it (See 1A).
NOTE: Do not pour media into standpipe or filter will fail under operation.
HINT: If you can not find the cap or cardboard for the install you can use a cup
to cover the standpipe.
B. Carefully pour in correct amount of media into filter, as supplied. (See 1B)
NOTE: Check to confirm that the standpipe is centered in the opening of the filter.
C. Remove cap from stand pipe.
2. Assemble Valve to Filter
CAUTION: Do not lubricate any part of the Rim, Seals, or O-Ring
A. Loosely pre-assemble both halves of the clamp with one screw and one nut,
turning the nut 2 or 3 turns. (See 2A)
B. Install clamp around tank and valve flange, and assemble second screw and
nut. (See 2B)

C. Place valve O-ring around valve base. (See 2C)
D. Insert Filter valve into the tank neck, taking care that the center pipe slips
into the hole in the bottom of valve. Place clamp around valve flange and tank
flange just enough so that the valve may be rotated on tank for final position.
Final positioning to be done later. (See 2D)
3. Plumbing the Filter
CAUTION: For 2" Valves only, Teflon tape has been applied to the unions for you. It may be necessary to apply
more Teflon tape if the valve leaks upon installation. DO NOT attempt to use ANY sealant other than Teflon tape,
as this can cause the valve to crack or leak immediately or over time. DO NOT over-tighten the unions. HAND
TIGHTEN ONLY, DO NOT USE ANY TOOLS. Please be very careful during installation, valves where unions have
been over-tightened and/or any sealant or putty of any kind has been used, will not be covered under warranty.
A. Attach unions to valve. (See 3A)
B. Once unions have been attached, glue pipe from pressure side of the pump
to slip fitted side of union leading to valve port marked PUMP. (See 3B)
C. Glue return line to pond to slip fitted side of union leading to valve port
marked RETURN. (See 3C)

D. Glue waste line from filter to slip fitted side of union leading to valve port
marked WASTE. (See 3D)
NOTE: Do not decrease size of waste line.
E. Once valve is in final position and plumbing is set, tighten both sides of
clamp alternately and evenly. Use a properly sized large screw driver and
tighten firmly to obtain a good seal. (See 3E)
F. Be sure to place vinyl protector caps over ends of screws. (See 3F)
4. Initial Startup of Filter
CAUTION: TO PREVENT DAMAGE TO CONTROL VALVE SEAL, ALWAYS TURN PUMP OFF BEFORE TURNING
THE HANDLE.
A. Depress control valve handle and rotate to filter position. (See 4A)
Note: Let Filter Establish for 4 to 6 weeks prior to your first backwash.
B. Prime and start pump according to pump instructions. We recommend direct
drive self priming pumps with all Ultima filters. (Or check with your dealer for
alternative pump, should be high flow.) See Chart on page 3 for pump sizing.
C. Once water flow is steady, check for leaks.
NOTE: Please use appropriate pump for filter size (i.e. If your pond is 2000 gallons and you buy a 4000 gallon
filter use 4000 gallon pump as well).
HINT: Note the initial pressure gauge reading when the filter is clean. (It will vary from pond to pond depending on pump
and general piping system.)
NOTE: During initial clean up of pond water, it may be necessary to backwash frequently due to unusually heavy initial
dirt load in the water. Do not install filter on a pond with heavy algae content (i.e. pea soup). We recommend a water
change if the pond is really dirty.

Winterizing
1. Turn off pump
2. Completely drain tank by unscrewing drain cap at base of filter tank. Leave cap off
during winter.
3. Depress valve handle and rotate to Winter.
This will allow the water to drain from the valve.
Leave valve in this position when not in operation.
4. Startup after winter, install drain cap, take top off, stir up media, put top back on, put
valve into backwash position, and turn pump on. Backwash then rinse.
PLEASE REALIZE…
Pure clean pond water is a combination of many factors, one is the proper Aqua Ultraviolet UV system, and another is ade-
quate filtration and proper water flow. The higher flow rate through the pond turns the water more clear.
Now you can filter any pond, large or small and keep it crystal clear all year round without a huge expense.
If Your Filter Is Buried
1. Make sure pump is off
2. Take filter offline by disconnecting unions.
3. Loosen clamp screws and remove clamp.

remove the water from the filter. DO NOT REMOVE THE MEDIA.
6. Reattach the valve see page 8 for valve reassembly.
7. Depress valve handle and rotate to winter.
This will allow the water to drain from the valve. Leave valve in this position.
Backwashing Your Filter
NOTE: How often you backwash depends on the number of fish, how frequently you feed them and the season. We recom-
mend cleaning once a week. In heavy fish loads like in aquaculture twice a week or more is necessary.
WARNING: Before depressing and turning the valve handle always turn off your pump. Leaving the pump running while
changing valve postistions compromises the seals on your filter. Damage caused by leaving the pump on is not covered
under warranty.
