Tests show that due to lengthy activation times, many powdered and granular enzyme formulations get washed through your system before they can even begin to approach peak effectiveness. They often do not contain sufficient microbial nutrients to stimulate proper multiplication of bacterial enzyme colonies and because of their inherent properties, their odor control ability is minimal. Cold weather conditions also cause enzyme activity to greatly reduce as bacteria become dormant. Most enzyme formulations are not properly balanced so some ingredients are used up too quickly while others flush through the system before becoming active. En-R-G activates and maximizes your enzymes.
