Ecocel 4500 External Filter
Ponds up to 4,500 litres
Water is pumped into the filter via a stepped hosetail in the lid and is sprayed into the filter via a sprayhead. This adds oxygen to the filter.
The water passes down through a sheet of profiled open cell foam which removes solids. The water then travels through plastic cypripak biomedia colonized by beneficial bacteria before returning to the pond via a 40mm outlet.
