Function description
The filter pump pushes the water into the pressure-tight container where it passes through sev-
eral cleaning stages before returning into the pond.
Cleaning stage "Filtration"
The water flows through the foam filters. Mechanical soiling is retained by the foam filters. Sus-
pended matter and bio sludge settle on the container bottom. Useful bacteria settle on the foam
filters, cleaning the water biologically. Their effect starts at a water temperature of +10 °C.

Red (30 ppi)
Cleaning stage "UVC radiation"
Water is subjected to UV-C light from the UVC clarifier. Green algae die, pathogenic agents are
killed.
Bypass
The bypass ensures that only approx. 70 % of the water is subjected to UV-C light. This guaran-
tees sufficient radiation even at high flow rates.
Biological cleaning effect
The maximum biological cleaning effect is achieved when the foam filters are fully colonised by
filter bacteria. On new foam filters, colonisation may take several weeks. Adding starter bacteria
can significantly speed up colonisation.
Cleaning the foam filters
You can use the soiled water from cleaning the foam filters to fertilise your garden.

Properties
High flow rate
Colonisation of bacteria for nitrification, which turns ammonia first into ni-
trite, then into nitrate
Lower flow rate
Colonisation of bacteria for nitrification and denitrification, which turns ni-
trate into nitrogen
