I run it in my 90 stocked with Trophs. Personally I like it, when I added the trophs, the nitrates started climbing (the tank had been cycling for 2 years) - it immediately brought them down to negligible amounts.
I am pretty sure it is helpful when suddenly increasing the bio-load in a tank, as far as it resolving your driftwood problem, I'm not sure. I really can't see any negative's from putting it in though.
