I have just turned my 55g tank into a salt water tank. I would like to do a reef tank. Yesterday I filled the tank with 30lbs of dry sand and 20lbs of live sand, 15lbs of live rock, and salt water. I plan on adding 20 more lbs of live rock this weekend and a couple sails and sand shifters. i will provide some picture of my setup soon. i'm running no sump, just two hang on filters that were on my freshwater setup, a decent size protein skimmer, one large heater, and two power heads.
