FLFishChik Posted August 20, 2022 Share Posted August 20, 2022 (edited) I have a 5g Betta tank that I make “Tannin Tea” for and add a little at every water change. Today when I did tank maintenance, I added more than usual, making the tank appear very dark ( you can’t tell by the photo because my phone compensates for the lack of light. You’ll have to trust me here). But, it got me wondering if there’s such a thing at “too much” tannin?
