Sunterra Pond Filters

Our bio-filtration products utilize a dual filtration system consisting of both mechanical (foam filters) and biological (bioballs) processes. The bio-filters' watertight pressure containers ensure leak proof performance, while our unique self-cleaning feature ensures filter performance is always working properly. For ultimate filtration performance, we have combined the same features of the mechanical and biological processes of our other filters with the added benefit of ultra-violet light filtration. UV radiation eliminates the algae that survive the normal filtration process, creating a clearer and healthier water garden.

	1) Mechanical Filtration Water is pumped into the filter creating the necessary pressure to begin the mechanical filtration stage. There are two phases in the mechanical filtration stage – coarse and fine filtration. Each phase uses a specially designed foam filter to effectively remove all sizes of unwanted debris.
	2) Biological Filtration The biological filtration stage begins when water reaches the bottom of the filter. This stage uses bio-balls providing a habitat for beneficial bacteria to grow. These bacteria naturally convert harmful ammonia and other wastes into healthy nitrates that fertilize aquatic plants and support a healthy pond environment.
	3) UV Filtration The final filtering stage uses a low voltage, Ultra-Violet (UV) light located in the middle of the filter. Exposure to the UV light kills algae as the water passes upward through the filter on its way back to the pond.
