I am going to set up another tank in the near future. So I have been picking up supplies as I can. I have a 55 that is 1/4 full of crushed coral that was in an active system and the other 3/4 is full of live rock. I have circulation and heat in the tank. All this material came from an established system that was taken down due to selling a house. What do I need to do to keep the rock alive and well.
