High-performance, low effort – convenience for pond owners. A regulated, high-quality filter system spares every pond owner a lot of irritation. You can do all you want in terms of cleaning the pond – however only the implementation of a filter can sustainably influence the quality of the water. Optically clear water is not necessarily healthy water. A pH test provides precise indications in this regard. The ideal value is 7.2 pH. Filters do not only remove pollutants. They also ensure the removal of organic compounds that, in heavily populated ponds can lead to excessive nitrite values which can make life difficult for your fish. The OASE complete filter systems make this really quite simple.

Oase Biotec 10.1 The Biotec 10.1 is designed to eliminate cloudy, dirty water and algae growth by converting ammonia, produced by fish waste, dead plants, etc., into nitrite and then into relatively harmless nitrate using a natural process. This filter is designed to be used outside of the pond and cannot be pressurized. The Biotec 10.1 comes with a temperature indicator and a pollution indicator to indicate bacteria activity and show when maintenance is necessary.

Oase Biotec 18 Screenmatic Most ordinary filters are designed trading off between effectiveness and low maintenance. Often a very effective filter will require constant attention and filter cleaning, especially when the pond environment introduces larger particles such as fish waste or fine gravel into the filtration process. The Screenex particle screen was designed to make the Biotec Screenex Filters a solution that does not compromise between effectiveness and ease of use. With Screenex technology, larger particles are trapped and removed from the water before they can clog the filter pad pores and reduce filtration efficiency. Flushing the screen requires only the twist of the flow regulator. Of course, the Biotec 12 / 18 / 36 offer all the benefits of their smaller siblings. Biological filtration removes excess nitrogen compounds from the water to control algae growth. Filter pad cleaning is hassle-free. Compatibility with other OASE equipment ensures optimal performance. In addition, the Biotec 18 and 36 have a second filter chamber (factory filled with OASE Phosless) which can be used with additional filtration media of choice.
