I have some wood collected from a local river that i was using for herps but as i cant find any wood at LFS i was thinking of using some in my tanks. I have used it for reptiles before but not in any of my aquariums in the past, there are a lot of pine/fir maybe cedar trees in the area and the wood has no bark etc left to tell what type of tree it is from, is there anyway to know if it is safe for fish or not? I know it needs to be baked or boiled to clean it as well.
