hi im new to saltwater stuff i've had freshwater for 5 years now and i just love watching the fish but we just bought an 150 gallon tank that was fresh water and we turned it into saltwater we went out and bought salt and sand and 4lbs live rock to start with. we reused 3 power hearders and the filter that hangs over the ledge which is the only one with carbon in it and the heater. it has the regular lighting hood. I need help to know what to get next. i put in a domino damsel and a yellowtail blue damsel and 2 snails and a feather duster to start with and just bought 5 more lbs of live rock. we want it to be colorful. i dont know where to go from here i guess we want some reef and we most definatly want fish. any help would be apreciated. i would like to know specific and links to things to look into for options vs cost. thanks
