How do you guys go about collecting and treating wood for the aquarium? Obviously, well decayed wood and fresh wood are both inappropriate for the aquarium; is there a sweet spot of "deadness" you have too look for? Which trees have wood that lasts long in wet environments than others? Does it depend on where the wood comes from on the tree? I would think roots would do better in wet environments. Can you do anything natural to the wood that will delay decomposition? Should bark be removed because I have never seen wood at the store with bark on it.
Sorry for all the questions! Thanks!
