I've been lurking for two months now and have really learned a lot from all of you. thanks! I am about to help a friend of mine set up a 125 gal. tank as a plant tank. We were wondering if we could use a section of a cypress stump that had been soaked for a week in a ten-percent solution of bleached and then thoroughly dechlorinated? Any opinions?
