Using Tri-Zyme in your holding tank is your best assurance of an odor-free and trouble-free sanitation system. Simply flush 2 scoops into your toilet after every tank pumpout. The natural enzymes grow in the tank and work at breaking down waste material and eliminating odors. Tri-Zyme For Holding Tanks contains a small amount of chemical deodorizer to cover any existing odors until the enzymes have a chance to work.
