I bought a piece of driftwood thats supposed to be for reptiles but the guy at my lfs said it wood be ok to put it in a fishtank so I triedit. I soaked the wood for a while before putting it in. The next day i put it in my tank and overnnight a bunch of whiteish slime is comming off. I removed it and soaking it again. All my fish are fine. Do you think I could try it again or just leave it out of the tank?
