I have a 28g jbj nano with led lights. 40 lbs of live rock with 8 fish. (2 small clowns) tang, cardinal, wrasse and 3 small blennies. I have a little cloudiness to my water for about a week and a half. I thought it was a bacteria bloom but it did not clear up. I am running a tunze protein skimmer and i would like to have advice in clearing up my tank to be crystal clear
