My dad has the percula 90 and the protein skimmer has a kind of airline pipe that comes off protein skimmer with a adjustable valve in the middle of the pipe, and on the other end is a suction pad with what looks like a co2 diffuser. Any idea on what it is and where it needs to be? Below water/ above water etc. Not sure if it helps but the top of the protein skimmer where its ment to get all the dirt has aload of bubbles in it. Any ideas?
