Scott, I see no need for banter; there are exceptions to everything encountered in life...Good luck on this venture, I'll stick with what has proven to work for me over time, and that's pretty much where we all seem to evolve in Discus keeping. Since we have only had 'running water' in this part of my state for twenty years, it is a precious commodity, and I'm working on reclaiming all that I throw away. Our septic systems can't handle an overly large amount of water without a lot of grief either..cheers, and hopefully we won't see you on the 'what's wrong with my Discus? threads..Gary
