3.5 Function description
ProfiClear Premium Compact combines the removal of coarse dirt particles and biological filtration in one
unit. Screens (60 μ m) 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 an integrated micro-controller 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 by the ProfiClear Premium Individual
Moving Bed Module when installed as a gravity fed system.
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
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
bio-elements even at high flow rates. The biological system is self-cleaning and does not need additional
maintenance.
60 l of Hel-X biomedia are able to break down the nutrients from approx. 408 g fish food per day,
given optimum conditions. If required, this can be increased to 80 l or 85 l, i.e. 544 g/day or
respectively 578 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.
3.6 Easy Garden Control System (EGC)
This product can communicate with the Easy Garden Control-System (EGC). EGC allows convenient
control in the garden and pond via smartphone or tablet, and ensures maximum convenience and
reliability. Information about EGC and the possibilities it offers can be found at www.oase-
