I think you would be OK to vaccum the sandbed. But, like Shaun said, don't do the entire tank all at the same time; half the sandbed at every water change.
Dave, remind me again - how big is your tank, and how many lbs of live rock do you have?

I have a 55 gallon with a 20 gallon sump, not sure how much live rock we have but its pretty packed. I would estimate over 60 lbs probably. We stirred up the sand a little in one spot and there was this gas cloud coming out of it...pretty gross. Would love to get a goby or anything else that could help clean it up for us. |
Be very careful as you begin to clean your sand bed up. An old bed can be full of toxic gas, which is not necessarily bad until it is disturbed. Start with very small sections of the bed. Spread this out over weeks, if not months. Otherwise, you could nuke your tank. |
If there is a lot of gas, I would recommend siphoning small sections before disturbing the sand bed.
