Function description

The ProfiClear Premium XL Moving Bed Modul is designed for biological filtering of pond water. Pond
Pads are used as filter material. A mix of Pond Pads and Hel-X biomedia is also possible as an alter-
native. (→ Commissioning/start-up)
Biomedia (Pond Pads, Hel-X) ensure the effective break-down of nutrients and contaminants in the
water. Over the course of time, their surface is is colonised by bacteria responsible for nitrification and
denitrification. They clean the water before it leaves the container. The fluidized bed process (action of
the water flow and oxygen supply) and the bypass technology ensure optimum movement of the Hel-X
biomedia even at high flow rates. The biological system is self-cleaning and does not need additional
maintenance.
The development of the micro-organisms in the filter takes several days. It can be accelerated by add-
ing biological starter bacteria.
BioKick contains millions of active micro-organisms. They start cleaning the water immediately. The
biology in the filter is fully developed within only a few weeks.
Nitrification is the process by which ammonia/ammonium and nitrite are removed from the water by
special bacteria. These substances can build up in the water, for example as a result of fish food and
fish excrement. Ammonia is particularly toxic for fish.
Nitrification takes place in two steps. In the first step, the bacteria convert the ammonia/ammonium
into nitrite. In the second step, other bacteria convert this nitrite into nitrate, which although non-toxic,
promotes the growth of algae. Both steps use oxygen that is taken from the water.
Denitrification is the process by which nitrate is broken down to gaseous nitrogen. In the event of a
low oxygen content, the bacteria use the nitrate nitrogen as a source of oxygen and convert it into at-
mospheric nitrogen. Atmospheric nitrogen cannot be used by algae and aquatic plants.
