Econiche efficacy? Does anyone remember what the efficacy rate is for Econiche? And how it compares to the efficacy of this cometitor? How does Econiche compare in the percent reduction of ecoli shedding? Seems like I remember 98% or some such figure. But Bioniche's web site is fairly lame for finding this basic information on it very quickly. Didn't have any more time to look. Anyone have these answers?
