I strongly suspect that your chances of getting your wood to go back to
normal are just about zero. I can't think of any way to stop that decay
that wouldn't also kill everything else in the tank. You best bet would
probably be to get rid of the wood you have now and get hold of
some proper driftwood that won't go into decay on you.

I agree with Michi. Dried for a couple of years makes it suitable for
your fireplace, but aquarium driftwood should be completely dehydrated,
and that takes many years in dry conditions. I've used less than perfect
wood before, and sometimes I get away with it, and other times it goes
into rotting mode and I need to pitch it.

Ouch!
Well, thanks so much for the advice, anyway :-
