I've got a cpr bac pac 2r on my 55 ......its been going for about 3-4 months now.....in the return chamber there is at least one slug(small-about 1/4 inch) and what appears to be a large number of copepods/amphipods....plus just plain old scum......should I remove the skimmer and clean it up or just let it be......it does a gr8 job......very seldom produces bubbles and empty about 1/2 cup of dry skimmer stuff twice a week..........
