Do not know for sure where it came from was sitting in my backyard for campfire wood. It has some algae on it and I would rather make sure it does not have some wierd bug or something on it. So I will just have to wait till it ready.
Found out the peice of wood is too big for my tank. So thought I would place an ad on the local Craigslist and sell it. It is such a cool peice I am sure somebody would like it for thier tank.
