Manufacturer Description:

A contained body of water is subject to conditions such as dirt, insects, algae and decomposed vegetation that affect the water clarity and health. A filtration system is needed to balance the ponds ecosystem. This filtration system must match both the power of the pump and the volume of the water garden. All Sunterra filters use mechanical and biological filtration. The mechanical filtration process uses foam filters to trap debris. While the biological filtration uses biological ball (bio balls), that have large surface areas used to nurture beneficial bacteria. This beneficial bacteria converts harmful pathogens into useful nitrates. Both types of filtration work together to provide a clearer and healthier pond. The Sunterra Bio-filters utilize a dual filtration system consisting of both mechanical (foam filters) and biological (bio balls) processes. This particular Bio-Filter cleans ponds up to 1000 gallons. It is recommended for use with pond pumps capable of pumping water from 850 to 1250 gallons per hour. Read more
