In this way, the filter works in pumping mode: however, it can also work in gravity mode. The tank must be equipped with a bottom outlet, skimmer and suitable piping.
The dirty water from the pond goes into the first filter chamber, where the brushes hold particles, algae, leaves, etc.
Freed from these residues, the water then passes through the various biological chambers of the filter. These chambers contain carriers, nitrifying bacteria that develop on the surface and participate in biological purification.
This type of filter requires maintenance, which only consists of keeping the brushes in an acceptable cleanliness and regularly cleaning the chambers - emptying the sludge.
