Protein Skimmers are a combination of a biological, mechanical and chemical filter. The principle works as follows: the surface of an air bubble attracts substances dissolved in water. Due to the attraction of air bubbles, chemicals, dirt particles, dyes and algae are concentrated.

Aquaforte Tornado III Protein Skimmer
The Aquaforte Tornado Protein Skimmer is a renewed model with ball valve for flow control and special new bio rings for even better mix of oxygen. Thanks to the ball valve it is much easier to adjust the correct water level. Through a 4mm air connection and supplied flowmeter an air pump continuously pumps 0,5l/m (30l/h) air into the filter. This pressure ensures that the foam is pushed out of the filter through the foam 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 water. Due to the attraction of air bubbles, chemicals, dirt particles, dyes and algae are concentrated. Air is mixed with water by means of an air pump. By forcing this mixture through the filter material (bio rings) to a lower outlet, a very long contact time between water and air is created. This changes the surface tension of the water continuously and creates a firm foam. This foam is separated from the purified water by a perforated cone and discharged. Substances dissolved in the water such as phosphates, ammonia, Hemic acids, dyes, proteins and a number of heavy metals are filtered out of the water and discharged by means of the foam. Read more

The Fresh-Skim protein skimmer, is an extremely efficient fresh water protein skimmer due to their large volume. As the proteins are directly removed from the water column, the filter system will have a significantly lighter job to do. The biological load of the water will be lower, besides the fact that the air bubbles will increase the oxygen level of the water. This will aid both fish growth as well as water clarity. The recommended flow is based on a contact time of at least 1 minute which makes the Fresh-Skim also qualified as a safe ozone reactor. When ozone is used we recommend the use of a residual ozone destroyer for the air outlet to prevent the release of ozone in the air. There are 2 options for mounting the redox electrode into the pipe system: in between the pump and the skimmer (before the ozone dosing), or in the return pipe from the skimmer (after the ozone dosing), or better, using both. Bigger skimmers are available on demand. The ceramic air diffusers should be replaced yearly to maintain maximum efficiency. The skimmer should be fed with pre-filtered water (i.e. after a sieve- or drum filter) and the water should return to the pond freely by gravity, without any head pressure.
