Alright, Ive had this sapphire skimmer in my solana for about 2 weeks and have never properly got it to adjust. The first time i plugged it in it worked perfect with no problems. but as the weeks went by, I slowly started to see less and less action. then today i looked at my tank and the skimmer was pouring clear water into the skimmate cup. The skimmer comes with a gate valve that your suppose to be able to adjust, but I havent even had any water go through the gate so adjusting it does nothing. Is something wrong here or what?
