Okay, I have a skimmer that has been working great for a long time, no problem there. All I have ever done is empty the collection cup every third day and tweak the flow here and there. Now it seems that the cup needs to be emptied only once a week. The bubbles are still as always, just not much going over into the cup. Has my tank miraculously 'self adjusted' or is the skimmer going bad. Should I restrict the outflow even more and force the cup to fill, even though it is not really greenish water in there?
