Sander Fresh-Skim 300

  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.
