I've heard a few times that fish like tannins, and was wondering what the source is for that. What are the benefits supposed to be.

I'l grant that they clearly aren't hurting anything. My water parameters are fine, the fish are happy, and the plants are growing, but it is getting unsightly. Not high on my priority list, but it would be nice to clear up.
