I just want to be sure..... I am taking down a red sea 170, and setting up a new red sea .... new sand, water and using the old rock from transfer tank. I should be fine, to do this and add the fish and a few of the corals, correct? LPS corals. and a change of about 20 extra gallons. Not sure if I should add bacteria and wait a bit, because it's been a while since I've done this. any help would be appreciated. Not in a hurry, this tank sat empty in my living room, for a month.
Thanks guys :)
