Ok I posted about this awhile ago but it got lost. I found this wood I would like to make into driftwood decor for my tank. It was much bigger but I broke it down (and found an ant infestation. The other piece was unsalvagable and burned) How do I prep this for my tank? I am about to pour boiling water on it and let it soak for a few days but what else do I need to do? There seems to be some rot. I am planning on throwing some feeder guppies in the water in a few days to see if anything in the wood is a horrible poison and kills them. I am very concerned about adding this in with my fish! I love these fish and if they die because of a piece of wood I am going to be irate! SO any suggestions?
