Now I have to decide what to do. Taking the wood off is the most obvious
choice, but it implies a mayor change to the tank set-up, which is rather
difficult in its current location. Considering that the wood wasn't
completely "green", I'd like to know your opinion on the following course
of action:
1) add activated carbon to the filter, to remove as much organic matter as
possible
2) do large (30% - 50%) weekly water changes
3) dim the light
All this waiting for the plants to grow enough to starve the algae of any
nutrients.

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.

Cheers,

Michi.
