Question: How to Make Driftwood Sink in an Aquarium
Options:
So, you found a nice piece of driftwood and want to add it to your aquarium, but it won't sink to the bottom.  Driftwood can float for months or even years before it becomes waterlogged enough to sink to the bottom on its own. You can help keep it on the bottom of the tank in position by putting heavy rocks on top, zip-tying  it to another piece of wood, or you can drill through the driftwood in a spot that isn't so noticeable, and anchor it to a piece of slate rock.
