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 occuring bacteria that settle on bio-elements.

	Easy handling and cleaning
	Cleaning indicator automatically shows the degree of pollution and when the filtered biomass must be removed
