Function description

The ProfiClear Premium Moving Bed Module is designed for biological filtering of pond water. Hel-X bio-ele-
ments are used as a filter medium.
Hel-X bio-elements ensure the effective break-down of nutrients and contaminants in the water. Over the
course of time, the surface of the bio-elements is colonised by bacteria responsible for nitrification and denitrifi-
cation. 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 bio-elements even at
high flow rates. The biological system is self-cleaning and does not need additional maintenance.
The development of the biology in the filter takes several days. It can be accelerated by adding BioKick 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 oxy-
gen content, the bacteria use the nitrate nitrogen as a source of oxygen and convert it into atmospheric nitro-
gen. Atmospheric nitrogen cannot be used by algae and aquatic plants.
OASE recommends: If you are giving your fish large amounts of food, ensure that there are sufficient aquatic
plants or change the water regularly.
