ok yall. i got that 20 gallon shrimp tank in the works. and i was wondering, besides water changes is there any way to get a piece of driftwood to stop releasing tannins? or at least reduce the color change of the water? the wood i have is a chunk of elm that i cut from a living tree. I baked it after i cut it to get the bark off and i also boiled it and soaked it before i did my paludarium. I tore down the paludarium but was unable to remove the wood. I did a better job with the silicone then i thought lol. but anywho it's turning my water very brown. I'm kinda annoyed. I know it will go away over time. not my first piece of wood. just wondering if anyone knows how to remove or reduce the tanins once the wood is already in the tank.
