Restarting my tank

[tlok]

I have a 90 gal tank which had been set up for approx 2yrs., started as a reef, but never got too far. Had live sand & rock with some small fish & crabs. Had to tear down due to remodeling. Would now like to really get into it... I restarted tank with same live sand & rock, but the sand and rock really don't look too good. Can i just purchase more live sand and rock and add it to tank or do i need to remove old and start with new? Is live sand and rock sold here good?

I don't really see where it would hurt anything to add it but you may want to put more sand and rock with it because depending on how long you have not had the sand and rock in some type of holder with circulation, everything on the rock and in your sand may already be dead.
