How does it work?

Stage 1 - Mechanical Filtration

Water is pumped into the pressure filter creating the necessary pressure to begin the mechanical filtration stage. There are three layers of media which include; coarse, medium and fine filtration. Each stage uses specially designed foam sponge to effectively remote all sizes of unwanted debris from your pond.

 Stage 2 - Biological Filtration

The biological filtration stage begins when the water reaches the bottom of the pressure 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.

Stage 3 – UV Filtration

 The final filtering stage uses a low voltage, ultra-violet (UV UVC) light located in the middle if the filter. Exposing the UV light to pond water kills algae as the water passes upwards through the pressure filter on its way back to the pond.
