You have to soak the wood until it becomes waterlogged. I do this in a bucket because my girlfriend got mad at me for putting it in the bathtub. It may take a week or so for it to become completely waterlogged so it will sink. Good start on your tank.
Thank you on the tank and info I'm just gonna keep it as is until it remains then. :p I have one more question for the driftwood could someone Id it. The wood itself has a redish tint, smooth, no odor and is red. It can from a swamp beavers made in lower Alabama. Yes I thoroughly cleaned it.
