I got a very nice piece of driftwood mounted on a rock from a friend. She had it her tank and had a big clado out break, so when I brought it home into a bleach dip twice for an hour each time. The thing is every time I time I let this thing soak in just plain water with prime the water gets a milky color to it and smell a little foul. it does seem to have a little bark left on it is really soft for some reason. I can leave marks in it with my finger nail. Now the other piece I got from her is bog wood and does not do that and is still kind of hard. I have no idea if I should put this in my tank or not????
