Installation guidelines with regard to the
clear water guarantee
In order to make any claims on the basis of the clear water
guarantee, the following installation guidelines must be observed.
Definition of clear water:
Clear water is achieved if the fish or stones at the bottom of the
pond can be seen at a depth of 1 m.
Selecting the right system
Please select the filter system using the following table (selection
criteria: pond size and with/without fish population).
Instruction for use
E Biological clarifying
The pores of the filter sponges form a large inner surface which
microorganisms can colonise. The red and blue filter sponges
differ in size and density. This creates zones in which the water
can flow at different speeds. Zones with a high flow speed (blue
filter sponges) favour the colonisation of microorganisms which
convert ammonium to nitrate via nitride (nitrification). Zones
with a low flow speed (red filter sponges) support the colonisa-
tion of anaerobic microorganisms which reduce nitrate to
nitrogen (denitrification).
F Water outlet with flow indicator
At the water outlet, the clarified water is fed back into the
garden pond via a pressure hose or a watercourse etc.
G Cleaning connection
When cleaning the filter, a drainage hose can be connected to
the cleaning connection which diverts the dirty water into the
sewerage system or onto a flower bed.
H Function switch
The function switch is used to switch between normal water
discharge into the pond (“Filter“) and the cleaning connection
(“Clean“).

Cleaning the filter sponges with the handle function
The filter sponges can be cleaned while the Filtoclear is
operational through hard “pumping” by pressing the cleaning
handle.
