This can be used to treat and maintain your septic system. It can be poured down the drain or toilet. One bottle is one treatment. It is easy to use since it is a liquid. It is safe for the environment and will penetrate grease, soap and other blockages you may have. We have had no trouble with out septic tank since we started using this treatment.
