 Cyprio Ecocel Filters serve two main purposes.
Firstly they act as a mechanical strainer for debris and clumps of algae, removing these from the pond.
Secondly they create a home for billions of beneficial bacteria which digest pollutants as the water passes over them.
The biological filter contains media of very high surface area to create a habitat for very high concentrations of bacteria.
The system should be run 24 hours a day to keep the bacteria supplied with pollutants. When used with a Hozelock Cyprio UVC, the Ecocel carries the Clearwater Guarantee |
