I'm setting up a 55g salt tank. Probably no corals. Just liverock, crustaceans, and fish. Already have the livesand (live Aragonite 35lbs), and about 15lbs of liverock in there already (about a week). Already have pods and a few larval somethings (radial symmetry, look like coelenterates or echinoderms under magnification). Have a "wet/dry" HOB (marineland something) and a biowheel penguin 300. 2 killer powerheads (big ones) with prefilter sponges, lots of current. Installing a skimmer (about 2 feet high, not sure of model), which I will HOB. Sound adequate? Lighting is 160w CF daylights.
