I am acquiring a bunch of odd looking sticks and pieces of driftwood. I would like to know what types of wood are safe for aquarium use, how to identify the types of wood, and the process in which to make them aquarium safe. Any links, tips, or info is appreciated. These are mainly a bunch of odd looking pieces of wood that my mother collected. I'd like to try to make use of them. She had stained some pieces that were in the shape of mushrooms, which I will obviously not be using.
