Septic Tanks add 1 Soluble Packet every month to maintain a healthy running septic system. For troubled systems add 1 to 2 packets weekly until the system improves, then resume monthly treatment to maintain the system. To apply, drop the packet directly into a toilet, let dissolve and flush.

One/month is more than enough for average homes. If you have a tank that is more than 1000 gallons or your home has four or more bedrooms, we would recommend two packets a month instead.

A proper septic tank maintenance requires routinary pumpings every 4 to 6 years, however, it is very common that the accumulation of excess solid waste starts sooner, due to the use of antibacterial soaps, detergents, and even simple fabric softener that kills the good bacteria. Thus the best thing to do is to use this monthly bacteria and enzyme treatment to ensure the population of bacteria on your septic tank is abundant and working actively. 

Yes, it not only keeps healthy bacteria working to break down the waste inside of your septic tank but also will help clean the lines leading to the tank.

No, just one for the whole house! Flushing the packet down any of your toilets will lead the bacteria into the septic tank.

The official 'shelf life' is 24 months, but if you keep it closed in the box in a dark, cool place, it will last much much longer.
