Sieve 3
General information
Sieve filters are mechanical filters that serve as the first step in the filtration process: filtering out coarse-waste particles. These coarse-particle filters remove leaves, fish waste and food residue from the pond water. This minimises the impact of coarse waste on the biological filter medium. The coarse waste is filtered out by a stainless-steel screen with openings that are 200 to 300 microns in size.
