I am starting from the very beginning and I have chosen to a FOWLER.I have heard and I was told by a fe members on the site that base rock can turn into live rock.Do I have to wait to add base rock or can I add it at the same time I add my live rock?I was told base rock is less expensive and I want a nice tank but don't want to spend a fortune.I have chosen Tukani live rock and I will have a 36 gallon tank.
