I made a trade for some misc. drift wood and hardwood to go into my aquariums. There was a piece of stump wood, which I'm primarily interested in as I wanted it for my 20gal high shrimp tank but on a couple spots on the stump it's burnt. The burn parts aren't very deep, it looks like it was just burnt enough to turn the wood black, kinda like if you were to darken wood with a blow torch. The guy said he had plans to just slice the burnt parts off which is what I was going to do but then I realize burnt wood is just a form of carbon which is what people put into their aquariums. So I'm wondering if once it's cleaned if it will be okay to to put in the tank with the couple of burnt spots. I'd rather not cut it if I don't have to cause I think it will ruin the smooth curves of the wood.
