I all. I want to go a different way with my tank. Was doing softies, nems, shrooms. I want to go more LPS & SPS. Have a lot of rocks that are covered with intrusive mushrooms that are dominating the tank. I want to replace rocks as I go. What would you recommend if you were doing your aqua-scape in an existing tank? What type of rock? Do you have to cure the rock before adding to the tank? If adding live rock do you need to acclimate?
