Function description
Figure (A)
A filter pump (only contained as a set in the scope of delivery) presses the water into a pressure-tight container, where
it passes several cleaning stages before returned into the pond. The soiled water resulting from cleaning the unit can
be used to fertilise the garden.
Figure B
Cleaning stage "filtering": The water flows through the foam filters. Mechanical soiling is retained by the foam filters.
Suspended matter and bio sludge settle on the container bottom. Usseful bacteria settle on the foam filters, cleaning
the water biologically. Their effect starts at a water temperature of 50 °F (+ 10 °C).

Ammonia -> nitrite -> nitrate reaction
Nitrate -> nitrogen reaction
Cleaning stage "radiation": The water is radiated with the ultra-violet light from a UV-C lamp. Green algae die, patho-
genic agents are killed.
Bypass: A bypass ensures that only part of the returning water (approx. 25 %) is radiated. In this manner a sufficient
radiation duration is obtained even at a high circulation rate.
Filter starter: The unit only reaches its full biological cleaning effect after a few weeks. The formation of a bacterial
community on the foam filters can be notably accelerated by adding filter starter bacteria.
