if you can fit most of it in a pot, try boiling for a few hours. I had to rotate mine within the pot a few times. I then weighed mine down in the tank with rocks for 4 days. seems wood might need to be fully submerged. After the 4th day mine fully sunk and has stayed down since. Those first few days there was nothing else I could do to get that thing to not float.Katie13 said:How can I get driftwood to sink faster? So far I've tried attaching the weights that you put on plants on it, but it's not done much of anything. I used 4. Any ideas to get it to sink?
