I’ve had this piece of driftwood (middle) in my tank for a few months and since it’s been in there it’s making the water look so green!!! I soaked the wood for two weeks changing the water every few days before it even went in and it doesn’t seem to be getting any better. Is this normal? When I do water changes I can see so many little bits coming off it. Don’t know if I should stick with it for a bit longer or take it out. My shrimp LOVE it for breeding.
