I have a 55 gallon FOWLR tanks and have two small fish and 8 or so turbo snails. I have had set up ad running for a little over a year. I have a question and wonder if it is possible to add more live rock to the tank. I like the way to looks now but think with more live rock and more building of the rock formations it would look much better? Do I have to cure it first? or can I just add? I got the original rock in the tank from MArco rocks and would like to just get more and add? Any thoughts?!?!?!?!
