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 colonisation of anaerobic microorgan-
isms 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
a drain 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 connec-
tion ("Clean").
I 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.
