The Miniflotor is a small but powerful air driven inside protein skimmer designed for aquariums upto 200 litres. Its characteristics are the two concentric reaction tubes. In the inner tube, the air bubbles rise and take a lot of water with them. This water falls down in the outer tube and takes lots of air bubble with it - down to the expansion cone. Here the bubbles turn and rise up again - through the counter current. This ensures a long reaction time of the bubbles in the water and an effective skimming. Included is a strong holding plate for fixing the unit at the aquarium frame and a lime wood air stone.
