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.
