I wonder. Since benificial bacteria "bennies" are living organisms, could one keep them alive in the medium by just using sweets to keep them fed? This would mean you don't need to apply them as often as is recommended saving money. I personally operate on the theory that the bennies added to my promix hp by the manufacturer will be there for the duration if one uses a source or carbs and doesn't apply anything harmful like h2o2 or chlorine. What do you all think?
