Pro-Pump/OX is an oxygen release compound. Introducing an oxygen source in an anaerobic environment (a low oxygen environment such as your septic tank or drain field) speeds up the system recovery process. As bacteria metabolize solids in the septic tank and drain field they consume oxygen. Eventually they will consume most of the oxygen in the system. Pro-Pump/OX temporarily increases the oxygen levels.
After adding PP-HC live bacteria, add two pounds of PP-OX for each five hundred gallon septic tank to the outlet of the septic tank the first day. Repeat every other week until the system is functioning properly. For badly plugged drainfields, double the dosage. See our bio-remediation kits for failed systems.
