Eco Strong’s All Natural Bio Enzymatic RV Tank Wastewater Treatment. Enzyme-producing bacteria-based RV toilet treatments are superior to; mineral/salts, toxic chemicals, and the newer enzymatic only products. All-natural biologic products have proven to be the most effective at breaking down waste, controlling odors, and preventing clogs than the other types of RV treatments. A biologic liquid product has many advantages over a powder/pod product. A liquid enables the biology to become active faster, disperses more evenly throughout the tank, and multiplies more rapidly. Our bio-enzymatic formula is enhanced by an all-natural odor counteractant which aids the biology in rapid odor elimination. Our six strains of all-natural enzyme-producing bacteria, combined with specialized enzymes, break down and reduce waste, fats, oils, greases, paper and hair, and more. Suitable for both gray and black water tanks.
