So, I've been searching for that perfect piece of drift wood for as long as i can remember and today, my search paid off as i pulled this amazing piece of wood out of a local lake which i now plan to put in my planted discus tank. I had great plans for cleaning it hoping to make it perfect when my friend says " so i suppose the wood is boiled-salt bathed- clean in the wild?" which made me think.. why clean the wood? my real question is, in a fishes natural habitat ( in this case my discus) conditions are terrible and dirty lol. so why is it necessary to clean the wood?; other than tannins which i don't mind much anyway. Thanks for any replies, just curious is all.
