Tornado III Protein Skimmer - Aquaforte

Finally back ! Renewed model with ball valve for flow control and new special biorings for even better oxygen mixing. Thanks to the ball valve, it is much easier to set the correct water level. Using a 4 mm air connection and supplied flow meter, an air pump continuously pumps 0.5 l/m (30 l/h) of air into the filter. This pressure ensures that the foam is expelled from the filter through the outlet tube.

The protein skimmer is a combination of a biological, mechanical and chemical filter. The principle works as follows: the surface of an air bubble attracts substances dissolved in the water. Due to the attraction of air bubbles, chemicals, dirt particles, dyes and algae are concentrated. By means of an air pump, air is mixed with water.

By forcing this mixture through the filter material (biorings) to a lower outlet, a very long contact time between water and air is created. This continually changes the surface tension of the water and creates a firm foam. This foam is passed through a perforated cone which separates the purified water and removes the foam. Substances dissolved in the water, such as phosphates, ammonia, humic acids, dyes, proteins and a number of heavy metals, are filtered out and removed by the foam.
