Alright, here goes. I've been doing tons of reading recently and have a couple questions. I have been reef keeping for about 5 years and have some skimmer questions. My LFS swears by a RED SEA Berlin. I have a 29 bow with a 7 gal. sump. I have been using the RED SEA powered by a RIO 2500. I had a bad hair algae problem for about two years until I finally started over. My tank has been running for about 8 weeks. Skimmer is wide open and not collecting anything. Plenty of bubbles but can't even flood the skimmer. I always assumed that the resaon I had very little in collection cup was due to the fact that I was seriously over skimming. I am starting to believe that it is rather a lack of skimming. I also am thinking that my horrible algae problem was due to this as well. My tank looks fine now but I want to keep it that way. No hair or red slime this time! Any suggestions? What should be collecting in the cup on a 36 gal with a maroon clown, yellow headed goby, and feeding every other day with a ton of janitors?
