Adding feed, organic matter or animals to the water will cause the foam level to rise, sometimes
substantially. Certain oils and other compounds will inhibit foam production. If the skimmer level
“bounces” or changes radically over a short period, there may be hydraulic issues with the way the filter
is plumbed and/or vented.
NEVER BLOCK THE DISCHARGE VENT UNION AT THE TOP OF THE FRACTIONATOR. This
will pressurize the unit, and void all warranties. If you connect any filters or ozone destruct equipment to
the top vent, the vent must remain free-flowing or at a slightly negative pressure.
To maintain an efficient fractionator the upper chamber must remain clean and the rinse system in the
upper chamber needs to be working properly. The chamber should be accessed through the top cover and
cleaned manually every 90 days or if the rinse system has been out of operation for more than 3 hours.
With a properly adjusted protein fractionator the water will be noticeably cleaner. Ideally aquarium water
should be clear and colorless. The closer to this goal the better.
