You didn't say but if you're not doing water changes and old systems can build up refractory DOC as well as shift to the production of labile DOC that is detrimental to corals so I would be doing 10% weekly for a while if you haven't in a while. SOme new quality maricultured live rock shipped overnight or airfreight (30 - 50 lbs only) I wouldn't bother witht he sand under the rockwork/aquascaping but I would carefully siphon out and replace the sand that is easily replaceable with new live sand.

Can yyo post some water parameters?
