I just picked up this 3’6” piece of driftwood and it refuses to sink despite weighing ~40lbs or so. Any ideas on how to get it to sink? It’s way too massive to weigh down with rocks, I cannot soak it in the bathtub, boiling isn’t feasible, and I don’t have a big enough bucket. Can I soak it in a used trash can as long as I rinse it off before adding it to the tank? I can’t see any other way of treating a piece this large. I also think it’s too big to attach a slab to Will it ever sink?
