Function description

ProfiClear Premium Compact combines the removal of coarse dirt particles and biological filtration in one
unit. Screens (80 μm) separate all types of dirt particles before the water reaches the biological filtration.
By separating the suspended solids, the filter removes most of the nutrient matter from the water.
Following this mechanical filtration, the Hel-X biomedia in the moving bed system carry out the biological
filtration of the pond water.
The control system with integrated microcontroller system automatically controls and monitors the filtration
process. The automatic self-cleaning function can be individually adjusted to meet the user's
requirements.
The drum filter unit ProfiClear Premium Compact can be extended with the pump chamber ProfiClear
Premium Compact/Classic when installed as a gravity fed system.
Hel-X biomedia ensure the effective break-down of nutrients and contaminants in the water. Over the
course of time, the surface of the biomedia 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 motion of the Hel-X
biomedia even at high flowthrough rates. The biological system is self-cleaning and does not need
additional maintenance.
40 l of Hel-X biomedia are able to break down the nutrients from approx. 270 g fish food per day,
given optimum conditions. If required, this can be increased to 60 l, i.e. 408 g/day.
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
oxygen content, the bacteria use the nitrate nitrogen as a source of oxygen and convert it into atmospheric
nitrogen. Atmospheric nitrogen cannot be used by algae and aquatic plants.
