Wear resistance
•The temperature of the liquid transported should not exceed +35 ℃in permanent operation.
•The filter is exclusively designed and intended for filtering garden ponds.
•The filter is not suitable for filtrating water whose temperature exceeds 40 ℃or falls below 8 ℃.
•Do not use in combination with oil, petrol or lubricant. The filter is not frost-resistant! Therefore,

According to the type of use, the optimal circulation cycle is dependent on various factors: fish popula-
tion, water plants, solar radiation and the desired water clarity. Of course, the other components of the
filter circuit must be harmonised with one another if necessary.
Basically, there are two distinctions:
1. Optimal pond circulation
This refers to how often the whole pond content is directed through the filter within a specific time unit
(circulation per hour).
The following values may serve as guide values:
•Koi pond/ fish pond:
◦1 × in 3 hours up to
◦2 circulation /circuits in 1 hour (without plants and with high fish stock)
•Garden pond/plants pond:
If the pond has no fish stock, circulation is not necessary at all. In this case, water and marsh
plants are a sufficient replacement/substitute for a filter system.
•Natural swimming pond:
◦Here the circulation cycle depends strongly on the plants and your own requirements.
◦The upper limit is 1 × in 2–3 hours, the lower limit is no circulation at all.
2. Length of stay of the water in the filter (length of stay)/filter volume
Here the real volume of the filter applied by pressure-less systems is interesting:
50167 (CBF-500) = approx. 120 ℓ
After a period of time of approx. 2–3 weeks, nitrifying bacteria settle in the filter sponges. These need
time in order to affect (have an impact on) the water.
The intended time that the pond pump needs to fully fill the filter lies between 1,5 min and 3 min with the
above-mentioned filter volume.
A well “run-in” filter needs therefore NO circulation cycle of 2–3 × per hour. It is definitely sufficient,
depending on the pond size, to have cycles of 1–2 × every 10 hours.

Calculation example:
A specific example: Our pump manages 10,000 ℓ⁄h. This means that, with our test pond of 100,000 ℓ
volume, the pond is completely filtered every 10 h, which means that the water flows through our pond
filter 2,4 times in 24 h and is clarified. Because our filter takes 250 ℓ of water, and in one hour 10,000 ℓ
are pumped into the pond filter, the pond filter is fully filled with water 40 times per hour. This means
that every 1,5 min the filter is fully filled. Consequently, our bacteria have only 1,5 min to have an effect
on the water and produce clear, filtered water.
We recommend according to your needs to find a reasonable compromise
between both systems to achieve an optimal pond filtration.
Intended use
•Products of this series are optimal for the cleaning of garden and fish ponds. If it is correctly
applied, the pond water is effectively cleaned.
•Biodegradable filter materials clean the water from bacteria through mechanical filtering.
Equipment features (partly optional)
•Efficient cleaning through ultraviolet light sterilisation before filtering.
•Powerful bio-filtering by means of large filters, multi-chamber system, easy installation and
cleaning due to its modular structure
•Water flow system that conducts the first step of the filtration reduces the pressure on the filter
mats and the maintenance
•Optimal filter holder design enables easy cleaning
•Dirt indicator
•Temperature indicator
Commissioning
1. Remove the top cover (1), take out the bio-filter sponges (7) and wash them.
2. Wash the filter mat (8) as well.
3. Exactly replace the cleaned filter materials in their places.
4. Place the filter on a firm, level surface at least 2 m from the edge of the pond when using a UV
lamp with the filter connected. It is essential that the filter is horizontal to avoid overflowing.
5. Lay the drain hose for the water outlet to the pond and the hose for the dirt outlet to the sewer
or to a flower bed with sufficient slope.
6. Saw off the hose nozzle (20) at the appropriate point.
7. Put the hose onto the hose nozzle (20) and secure it with a hose clamp.
8. Put an O-ring (19) on the thread of the hose nozzle (20). Then push the thread of the hose
nozzle (20) through the water inlet opening. Put a second O-ring (19) on the thread from the
inside and then screw the outlet nozzles (18) onto the thread from the inside.
9. Now connect the other end of the hose to the pump.
10. For normal filter operation, leave the dirt outlet closed with the cap (17) and a seal (15). If you
want to attach a 2-inch hose permanently, remove the closing cap to mount the hose.
11. Fit the top cover.
12. Supply the pump with voltage. The filter will now start to work.
NOTE:
The bio-filter is a biological filter system, so from its initial installation it requires some weeks until its full
biological efficacy. Is reached.

Cleaning and maintenance
Beware! Always pull the mains power plug of the pump before cleaning and maintenance!
The device should be cleaned as needed –see waste display (1).
1. Turn off the pump and the UV-clarifier.
2. Remove the filter sponges.
3. The sponges can be cleaned and squeezed out in clear
water. You can also use pond water.
4. Never use any detergent or soap as those will destroy the
bacteria inside the filter sponges.
5. Clean the filter tank with clear water, too.
6. It is not necessary to renew or clean all filter sponges at the
same time. If you just clean/renew a part of them, the im-
portant nitrifying filter bacteria are saved to a large extent and
need not to grow completely.
7 In case the base of the filter is too contaminated, it is rec-
ommended to drain the water completely from the filter.
8. After cleaning the filter, it is reinstalled as described.
At temperatures below 8 ℃or higher than 40 ℃, the device must not be operated! Therefore, empty the
filter and clean the device thoroughly. Remove all filter materials in order to dry them. Keep the filter
materials in a dry, frost-free place during the winter. Cover the filter housing so that no rain water can
enter. Empty all hoses, pipelines and connectors to the extent possible.
Before starting-up the filter again, install it again with the open side towards the exit.
