I was out in our concrete canoe today and spotted some old cypress lying on the bank. I hopped out and grabbed it. It appears to have little/no evidence of bugs eating it or any rot. What should I do to get it ready for my tank? Boiling will be tough to accomplish since I live in a small apartment with an even smaller kitchen. Should I treat it with anything? I know I need to soak it before trying to put it in the tank. Any experience with this sort of thing?
