Hi guys! Maybe a very similar question to this has been done already, but I found a nice piece of driftwood on the beach and have been soaking it in water for the past almost five days. I change the bucket of water every day. So how long until it sinks? I'm too scared to put it in my betta tank without being sure it's safe. But will I ever know if it's completely safe? No, right? Should I just forget about it and spend the five bucks for a lava rock? I just want the driftwood for java fern, java moss, and anubias nana. I would get multiple rocks or driftwood, depending on which I choose. Does anyone think I should soak it more? I only have a few weeks left to decide, mostly because I'm moving away to a place where fish stores are a minimum of seven hours away. And lastly, is this a dumb question?
