SO I was reading some older posts about treating wood and i got the general consensus soaking for a few days...anyways my piece I just got is about 2 feet long its actually pretty cool its like an old stump. Anyways. I put it in a rubermaid container and filled it with water, and Im just goign to let it sit there for a couple days, and change the water a couple times a day. Anyways My question is....Since I have to wait it down to stay in the container How am i going to weigh it down when I put it inside of my tank??? Will it Just soak water in, and end up staying submerged? thanks
