Function description
ProfiClear Premium Compact combines the removal of coarse dirt particles and biological filtration in
one unit. Screens 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 bio-
logical 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 Individ-
ual Module + 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 colonized by bacteria responsible for nitri-
fication and denitrification. They clean the water before it leaves the container. The fluidized bed pro-
cess (action of the water flow and oxygen supply) and the bypass technology ensure optimum move-
ment of the Hel-X bio-elements even at high flow rates. The biological system is self-cleaning and
does not need additional maintenance.
15.85 gal (60 l) of Hel-X biomedia are able to break down the nutrients of approx. 14.4 oz (408 g) of fish
food per day, given optimum conditions. If required, this can be increased to 21.0 gal (80 l) or 22.5 gal
(85 l), i.e. 19.2 oz/day (544 g/day) or 20.4 oz/day (578 g/day).
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. This oxygen 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.
Easy Garden Control-System (EGC)
This product can communicate with the Easy Garden Control-System (EGC). EGC permits convenient
control options in the garden and pond via smartphone or tablet, and ensures maximum convenience
and reliability. Information about the EGC and the possibilities it offers is available at www.oase-liv-
