Drift wood that never stops leaching

I have a nice piece of driftwood, that barely fits in my 75 gallon that has not stopped leaching tannins. I soaked it for at least 3 weeks in a utility tub and then got impatient. I have been doing water changes almost every other day just to make the plants viewable. This has been going on for about 3-4 months. Its too big to boil, so what can I do to make it stop?

No negative effects from carbon that I know of. There is a concern among some planted tank entusiasts that carbon can absorb fertilizers that you put in and then the plants starve. There is a thread about this that Hoppycalif started in the "Science of Aquatic Fetilizers" forum where someone actually posted which substances are absorbed by carbon and it seemed to suggest there is no need for concern.

In my opinion, carbon will not have any negative effect in a planted tank.
