Last week, I converted my 30g to a 55g and added new rocks with some pretty nasty stuff on them. Since then, the performance of my RS-80 has fluctuated. For example, I can get it dialed in at about 2-3 inches in the cup for a few hours then all of a sudden the skimmer startes going nuts and overflows the cup. Is this becasue of the varying docs going into the sump at any particular time? Sometimes I have to open up the riser tube all the way and it still pours into the cup.
