I have been using a cpr bak pak skimmer on my 26gal fowlr for about 8 months. It doesn't really collect that much skimmate and when it does, it is usually green tea colored.(Not the black stuff I keep reading about). I clean it about once a month and the collection cup never gets more than about 1/10 full. Also, when it collects, it usually only foams up at night. I've had the same 3 fish forever. An occelaris clown, 6 line wrasse and watchman goby. They are perfectly happy and all of my water parameters are in check. I do 20% water changes every 3-4weeks. Should I look at replacing the skimmer or is it working correctly based on my bioload and maintainence? i.e. " If it ain't broke, don't fix it"???
