Got a AquaC HOB Skimmer and its got to be over 10 years old so I do know this skimmer somewhat. One day I cleaned the pump out and also the skimmer itself because I was experiencing a problem. It puts out so much, not foam, but just water and barely any foam from my 75gal with LR no corals. Its going nuts because I'll empty it and an hour later its full again, WHY???? I can't figure it out. This skimmer has been pretty good for me but now its not worth a crap. I didn't want to have to buy new but.. Need help....
