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.

thing about carbon filtration is I dose excel. don't need the carbon soaking up all of that. i'm being kinda carful with that tank since most of my others have blackbeard in them. also this tank has hair grass. if I had a pressurized CO2 system I wouldn't be worried about it. ans as for the blackbeard i'm doing what I can to try to remove it the best that I can. thinking about an algae turf scrubber. but in any event i'm worried with not dosing excel or having the carbon soak up the excel, blackbeard my start to grow or my hair grass may die. the hair grass is fresh in the tank right now and not rooted in yet. i'm just starting to see new growth sticking out of the melting blades. Really don't want to disturb this sensitive plant.

then forget about the tannins and let it be. they soften the water or slightly lower pH - both good for growing plants.
or you can stop dosing excel for a while until the carbon clears out the tannins. then remove carbon ad dose as before.
