Dead Live Rock...?

[DSlater]

Really - darn. I would love to reuse it. Since the tank is 240 gallons - that's going to be a lot of sand to rebuy. But if there's no way to effectively clean it - then for sure, I'll have to buy more. Seems to be a lot of talk about live vs dry sand. Any thoughts? For my nano tank I bought live sand w/ the live rock but I'm starting to think that might have been a waste of money. The live rock will turn the sand live anyways...
