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 EVO 3000 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 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 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 Aqua Medic 3D needle wheel. This
water/air mixture is pumped into the reaction pipe where the organic substances are taken up by air
bubbles. Foam is formed and pushed into the foam cup. The purified water leaves the skimmer via
the outlet (Fig. 1, No. 12) and is directed by gravity back to the aquarium or filter sump.
4. Set-Up
The EVO 3000 is a "Hang on" skimmer.
