oh i seen i might just start off buying more live rock i want about 10 pound i only have about 7
Try to get a total of at least 16 lbs. since it's usually a good idea to have at least a pound of live rock per gallon. Before anyone else says it, that's not a hard and fast rule, but it's a good guideline to follow; you can sometimes get away with less or may even need more (depends on stocking levels and porosity of the rock).
I would just buy another 9-10 lbs. of dry rock and add that in. It will become live in time plus will be way cheaper than buying live rock and avoids water weight being a factor; you also will not have to worry about introducing any unwanted algae or parasites plus you'll probably avoid triggering another cycle.
