Fresh Water Protein Skimmer
Fresh-Skim 500
Skimming System in connection with air pump and water pump
Range of application/ Mode of operation:
The Fresh Skim 500 is suitable for garden ponds or breeding basins up to 140 m3.
This highly efficient skimmer is operated in a bypass mode, e.g. not the whole contense of
the pond (basin) will be let through the skimmer in one run. It should be placed so that it
will be fed directly from the relevant reservoir.
The skimmer must be installed in such a way that it can be fed constantly with approx. 18
m3/h water.
By pumping air through ceramic air stones, fine bubbles are produced, creating a foam
which will finally carry out protein and dirt particles into the foam beaker.
The water flow is created by a feed pump installed by the customer.
The foam beaker can take up a great amount of foam; for a continuous outflow connect
the foam with a drain. To prevent residual ozone from escaping a siphon has to be
installed.
If you use ozone we recommend to controle the redoxpotential (between 300-400mV) at
the water outlet of the skimmer.
