Cloudy, dirty water and strong algae growth are common problems in ponds. These problems are caused by floating particles due to an excessive supply of nutrients, dead plants, over-fertilized soil, acid rain, fish excrement and left-over food. These particles produce ammonia which is harmful to all living beings. OASE's unique Biotec Filter System transforms ammonia into nitrite using a natural process. The nitrite is then changed into harmless nitrate. Nitrate actually constitutes a healthy nutrient conducive to plant growth. The mechanical filtration process is carried out by various structured foam filters, the biological process through naturally occurring bacteria that settle on bio-elements. This filter will not eliminate blanket weed (string algae). Not for use in swimming pools or salt water.

Another unique feature of the Biotec  Screenex Filter System is ideal for large particulate removal. Special tool (included) allows for filter sponge cleaning without removal from the filer. It is equipped with a separate chamber for biomedia and the Screenex surface is manually flushed using the built-in flow regulator. Debris are rinsed away through side outlet.
