I've repeatedly used Food Lion water at 4.5 uS and gotten clear CS with the silverpuppy gen, so, it's not necessarily the higher initial conductivity that kicks a batch into going yellow but what the higher conductivity is caused by. [ie, not so much the contamination itself, but what the contaminant is]
Of course, water without any contaminants won't contain one that will kick the batch. Ode At 08:45 PM 9/26/2003 -0400, you wrote: >I use a SilverPuppy and make a gallon at a time in a glass jar.
