Organic waste such as residue from food, dead leaves, etc. that ends up in the pond consists of large chains of amino acids, also known as proteins.  Filtreco Protein Skimmer separate these proteins from the pond water.

The waste in the pond is broken down by enzymes and bacteria into small particles, which are small enough so that the proteins ultimately dissolve in the water. A mechanical filter can no longer remove these particles.

Before these particles are broken down further into harmful substances (ammonium, nitrite, nitrate, phosphate, etc.), and thus adversely affect the biological filter capacity, the proteins are first removed from the water by the Kinshi Protein Skimmers.

Proteins accumulate on the interface between air and water. Kinshi Protein Skimmers enlarge this interface to a size that causes the many proteins to accumulate here.

The water is mixed with large quantities of air in the inlet through a self-suctioning Venturi system. The water/air mixture is then distributed over a bio-wheel tower. This increases the surface area,giving the proteins more time to form better, more solid foam. On the bottom, the water runs through a sieve plate into a chamber.

Under the water surface, the purified water is carried away and the foam is concentrated on top to form a specially developed pyramid, where it is then removed from the system.

This is what makes the Filtreco Protein Skimmer extremely suitable for supporting biological filters in Koi ponds. In addition to proteins, the quantity of other materials such as colourants is also reduced.

The  Filtreco Protein Skimmer will remove organic waste including food waste, dead leaves, etc. that gets in the pond, consists of large amino acid chains, also called protein.

 Filtreco Protein Skimmer separate’s these proteins from the pond water.

The dirt in the pond from bacteria and enzymes break down into small particles, so small that the protein eventually dissolves into the water.

A mechanical filter can not remove these particles. A protein skimmer removes them before they are broken down further into more harmful substances (ammonium, nitrite, nitrate, phosphate etc.). Proteins assemble at the interface between air and water.


The water is mixed with air through a Venturi system. Then the water / air mixture is spread over Bio ring media. This increases the surface area, causing the protein to form a solid foam.

The foam is finally stripped from the pond water and dispersed from a 40mm outlet.

It will remove proteins and other substances such as dyes.
