ok cool, Oh and I had another question, I decided to go with the 22lb's of Premium live fiji rock from liveaquaria and plan to add 20lbs of base rock to it. Can I cure the 22lbs in my tank with out the base rock, then add the base rock later? When I add the base rock do I need to have it be under the live rock? If so do i need to have the base rock first beings I need to put down the rock then the sand? I just cant afford the live and base rock at the same time is the issue.
