I just started up a 55 gal Reef tank. I mixed the salt and my hydrometer read 1.022-1.023. From what i've read that is good. I added my sand, Aragonite, then crushed coral, another Aragonite, mixed it together, then on top added a bag of live sand. I leveled it off pretty decently. I am running an Eheim Ecco filter, and two Powersweep powerheads. I was told that the powersweep would last very long, so i will eventually move to 2xmaxi-jet 1200. I'm going to use compact lights, and a CPR Back pack skimmer. this is where my question comes in. What skimmer should I use for a 55 gal and should I use a UV sterillizer, and protein skimmer? also, does it sound like im on the right track? I'm adding my Live rock(Probably 15 lbs.) on saturday.
