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 OASE BioTec ScreenMatic Set 90000 features the BioTec ScreenMatic 90000² pond filter, The AquaMax Eco Premium 21000 OC filter pump and the Bitron C 110 UVC. The Biotec ScreenMatic filter is automated cleaning system incorporating a drive belt and 300 micron mesh screen. This facilitates cleaning by transferring solid waste product to a collection tray for easy removal. Solid waste is intercepted by the screen upon entry and a digital waste detection sensor measures waste build up, initiating clean cycles when the screen is sufficiently filled. Biological filtration of soluble waste is performed in bank of 16 filter sponges beneath the screen mechanism and natural zeolite binding media at the front of the filter.

The AquaMax Eco Premium 21000 OC filtration pump is perfectly suited to delivering an optimum rate of flow through the filtration system, passing of organic waste product and using very little energy to deliver a high performance. This pump features special features such as dry run protection and seasonal flow control for power savings in winter and can be controlled remotely using one of the OASE OC/EGC control devices (not supplied). The Bitron 110C ultraviolet clarifier mount directly onto the filter unit via twin outlets. This eliminates green algae and pathogens for clear and healthy water.

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.

I have now replaced the vacuum head of my Pondvac 5 twice and spoken to Oase to check I am using it as expected. I have always had great service from Water Garden.

Great support in planning and helping to calculate flow requirements for our large ponds to produce a cascading effect down several ponds and waterfalls.
