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 Blue 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 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 OR 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 Aqua Medic
mesh 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 Turboflotor Blue 3000 is a skimmer that can be set up in various ways:
1.
As an external skimmer, directly mounted on the aquarium: "Hang on", (Fig. 3).
2.
For use in the cabinet with a sump or under tank filter system (Fig. 4)
- next to the filter tank
- in the filter tank
