So get rid of it. Via RO. Once you have RO water, add a bit of peat. That should drop you into the range you asked for. And it should stay there pretty well. Add a bit more peat from time to time if needed. Not rocket science. Good luck. -- Dave Gomberg, San Francisco mailto:gomberg@wcf.com http://www.wcf.com/co2iron ----------------------------------------------------------------- ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
