Hi guys new to this site here and trying to get a 75gal salt FOWLR goin. I've had freshwater for a year or so mostly cichlids and I got bored with them so i gave them away and been researching a salt water setup for awhile now. I was thinking Clowns and Tangs in my 75gal I'm starting over so I purchased an fx5, protien skimmer,and live rock next. Is one power head enough? If so what do you guys recommend? I am also going to be using live sand for my substrate. Do i just need a cleaning crew for the sand or do you suggest something else? Thanks for your time. Any help is appreciated...

been waiting for someone else to say that for a while!
