Yesterday I renovated my 10 gallon housing a single male betta. I added a larger piece of wood and the water started darkening. Today the concentration of tannins is really thick, and I believe it's still releasing. I've only scrubbed the wood down in the sink with a toothbrush for treatment. I'm not sure if there's an upper limit tannin tolerance for bettas? Should I release some of the tannins out of the water, or is it a constant sort of thing?
