3. Theory

Protein skimming is a method of physical water treatment. It uses a phenomenon

known from our daily experience: the adhesion of surface active substances to air

water layers. If we add a drop of oil to a water surface, a thin film is produced with a

thickness of only one molecule. Surface active compounds like proteins behave in the

same way. The Turboflotor multi SL uses its air bubbles to create a large water

surface for the waste substances to attach themselves to. These air bubbles are forced

into the reactor-pipe in a such a way that they undergo a long contact time within the

counter current. Enriched with organic substances, they rise to the top and form a firm

foam, that is dehydrated and pushed into the collection cup. This method removes

organic wastes from the aquarium water before they become part of the biological

waste treatment cycle.

The Ocean Runner PH 2500 venturi pump draws the water out of the aquarium or the

filter chamber, mixes it in the pump housing with air, which is then cut into small air

bubbles by the

the reaction pipe where the organic substances are taken up by the air bubbles. Foam

is formed and is pushed into the foam cup. The cleaned water flows to the bottom of

the skimmer and is transported via two transparent tubes on the outside of skimmer

back into the aquarium or into the filter chamber.
