Re: Anti Tannins From Drift Wood
As far as I'm aware, there isn't a plant or an animal or any biological mechanism to rid your water of tannins. Plants produce tannins as a way to avoid being eaten. Tannins taste bitter, and bugs don't like bitter things, just like humans, so a plant that produces lots of tannins has a better chance of survival. Also, as I recall, tannins are rather large molecules, making it difficult for biological systems to break them down.
I think using activated carbon and water changes are the way to go.
