OASE BioTec ScreenMatic² Filter Sets

The OASE BioTec ScreenMatic² Sets are complete pond filtration systems consisting of a BioTec ScreenMatic² pond filter, an AquaMax Eco Premium Pump and a Bitron C ultraviolet clarifier. Each set has been comprised specifically to suit ponds of different water volumes and fish stock (species and stocking density). Based on this information, these automated-clean, energy efficient filtration systems will achieve an optimum rate of water turnover through the filter, tacking algae, solid and soluble waste, resulting in clean, clear and healthy pond water.

The BioTec ScreenMatic 40000² is a pond filtration system incorporating an automatic waste screen, foam banks and zeolite binding media. Incoming water is discharged onto the screening belt which intercepts organic waste down to 300 microns. A waste build-up sensor on the screen mechanism detects when sufficient waste has accumulated and automatically activates a cleaning cycle, offloading the collected solid waste into a large collection tray.

Beneath the screen mechanism are banks of OASE filter foams in different grades of coarseness. These filter sponges provide surface area for biological filtration of the mechanically screened water. Water passing through the system is also circulated through zeolite media which absorbs unwanted nutrients and gasses in solution. Supplied 100ml BioKick will immediately start the biological process. The AquaMax Eco Premium pump delivers an optimum rate of turnover through the filter, passing organic solids up to 11mm in size whilst consuming minimal energy. The Bitron 36C ultraviolet clarifier fixed to the filter box inlet will process algae/green water entering the system.

Pond Turnover Rates: The pond stocking levels will determine the required turnover rate which in turn determines the required pump flow rate. Typically, an ornamental pond without any fish will require the pond volume to be circulated at least once every 6-8 hours; an average stocked pond (with up to 1 kg of fish for every 1000 litres) will require circulating once every 4 hours; a heavily stocked pond including Koi (with up to 2 kg of fish for every 1000 litres) will require circulating once every 2 hours. BioTec ScreenMatic Set pump selections allow for increased flow lost through the filter foams as they become polluted with pond waste (see the importance of regular maintenance, below).

Pump Flow Rate: The pump flow rate, typically in litres per hour (lph) or litres per minute (lpm) is determined by the vertical lift, in metres, from the surface of the pond to the outlet pipe AND by the friction losses through the system. The narrower the pipe bore the higher the friction losses, so always use the maximum hose diameter. There will also be a friction loss caused across the filter media (foams etc), which will increase as they become polluted with pond waste.

Effect of raising the filter: Raising the filter height, typically for a watercourse or waterfall, will reduce the flow rate from the pump thereby increasing the amount of time it takes to circulate the dirty pond water through the filter. This effectively reduces the maximum pond volume that the filter system can cope with and may mean you will require a larger pump. Please contact us and we would be happy to advise you.

The importance of regular maintenance (cleaning): High flow rate = effective filtering. As the filter media (e.g. screen and foams) remove dirt and waste from the pond, so the friction loss across the foams will increase, thereby reducing the flow rate and the effective performance of the filter. It is therefore essential, especially for those systems with a raised outlet, to keep the filter foams clean. Fortunately, this is extremely easy with OASE BioTec ScreenMatic pond filters.
