About a three months ago I bought a coral box cloud 9 skimmer and hooked it up to my 150 gallon newly established mixed reef tank. Its sitting in 11 inches of water in my 40 gallon sump.the skimmer is rated for ranks between 200 and 400 gallons according to the manufacturers site. I’ve been having a difficult time getting it to skim. I can’t seem to get it to produce that thick foam. The bubbles it produces are very much like a boiling pot of water - unstable and sporadic. Does anybody have any advice or experience with this particular skimmer?
