Hello, I have a tunze 9002 nano skimmer in the middle compartment of my biocube 29, And I have never pulled sludgy skimmate out, ether nothing, or some crusties on the lid and around the top of the cone. Or if I turn the dial up it just fills with green water :S. The tank inhabitants are, 2 clowns, 1 coral beauty and 1 Yellow wrasse 3 snails and one hermit. Am I not getting allot of skimate because the bio load isn't very high? I have a small basket of Cheato in front of the skimmer thats doing well. I have youtubed tuneing a skimmer but am still unsure on really what it should be doing?
Edit: I have alot of sps doing very well, Little to zero nitrates, I feed the 3 LPS colonies once a week and my GBTA twice a week as well. I feed the fish once or twice a day, depending if the clowns beg :S
