Create a wish list:
Biological pond filters.
1 - Water enters the unit via a spray head, which is evenly distributed over a foam sheet.
2 - Solid particles in the water are trapped in a foam sheet.
3 - Almost solids free, the water passes through plastic biomedia where beneficial bacteria cleanse pollutants. The amount of biomedia contained in the filter increases in direct proportion to the size of the pond/filter to support a greater number of fish.
4 - Purrified water then passes up an outlet tube and back into the pond.
5 - Use the viewing hatch to observe the internal operation of the filter, in particular whether any maintenance is needed.
Suitable for ponds up to 5,000 litres.
