Ordinary cleaners contain surfactants that allow dirt and soils to redeposit and create odors. Nugen contains nanoparticulates, also called colliodal micelles that bind to waste, tissue, dirt, oil and grease making them insoluble in water and unable to redeposit. These nanoparticles further reach out and attach to the walls of the tank forming a "nano-shield" to create a self cleaning environment. The result is a cleaner and odor free tank 24/7. 2oz treats 40 gallons. Net weight 20 oz.
