I am using the Aqua C Urchin for my 58 gallon in the 29 gallon sump. Since day one I have gotten hardly any results. The production cup is full of extremely white foam that is produced very rapidly and turns into clear water. I was told at the fish store that my pump was pushing too much water through it and I have cut down from a Maxi Jet 1200 down to a Maxi Jet 600 which seemed to help at first and made the collection cup fill up slower but now it is producing those very white foam at a very rapid pace again. Is anyone familiar with this type of skimmer and is there anything I can do. If not what would be a good skimmer for my size tank. This is starting to get very frusterating. Thanks in advance.
