Going throug Hypo

I'd give it a try. Just set the rock in some saltwater while you monitor the situation.

In general, bacteria don't immediately respond well to a lower salinity, so how many are actually processing wastes may be a moot point with the water changes you're doing. If the bacteria are active, you might reduce the number of water changes you're doing.

But if you think everything is already dead in/on the LR, then I would agree to just leave it be.
