Ok well I have completed my change out from my 55gal. over to my 125gal last week and everything seems to be doing fine. Now my wife has decided she wants to have a 55gal F/O Tank. Can someone tell me exactly how to set this up. No live rock, no live sand, just plain sand and fake things for the fish. Am I right in saying that I will still need to get all levels up in the tank like cal., mag., and of course the ph and sal. I don't want to make this harder than it needs to be. So used of dealing with my tank that I think I an thinking to hard. What is your imput for this F/O.
