Contains premium natural microbes that reduce odors and digest organic waste, including fats, oils, and grease (FOG), carbohydrates, proteins, cellulose, and urea. Septic systems work by using naturally occurring bacteria to breakdown and liquefy waste. If the septic system doesn't work properly, backups, lawn damage and foul odors can result. The bacteria in SeptiTreat™ help replenish the natural bacteria in the septic system that can be overloaded by large amounts of waste, or excessive use of disinfectant chemicals. Only one 8 oz. bottle is needed per quarter for a typical household. The product is simply poured into the toilet and flushed. SeptiTreat™ may also be poured down a drain, followed by about a gallon of water.
