Oh yea, sorry I left out that I'm on well water. It's very soft, comes out of the tap at 6.0 and 28 ppms of Co2 per a test kit. It will aerate to 7.5/7.6, although lacking buffers, will go back to 6.0 in a tank eventually without buffering. _______________________________________________ AGA-Member mailing list AGA-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/aga-member
