I see thanx. Also what kind of powerhead would you suggest a good one to get. Because as of right now I only have 3 powehead: 2 maxjet 1200 series which ony give you 295gph and also a Hydro Korilla the 1200 series too which give you 295gph for my 75 gallon. And I want to bring my flow rate up higher because I getting a lot of build-up debri behind my LR and under my LR, which I'm tired of looking at it. What would be a good suggestion way to re-arrange my LR so that I don't get a debri build-up before I start place coral and get my tank stable. I don't have any sand bed in my 75 gallon. Sorry for hitting you so many question. I'm trying to learned how to do simple reef tank, which I'm having trouble right now specially keeping my cal. level stable because it keeps up and down.
Thanx
Jay
