Check your tank before using Bio-Clean.
Your tank may need to be pumped if any
of these three conditions are present:
  1. (1) Solids on top are more the 6 inches thick
  2. (2) Mineral ash on bottom is 12 inches or more
  3. (3) pH of the tank is below 6.5 or above 8

Always wait 2-3 weeks after pumping before
applying Bio-Clean.

The initial treatment is 1 lb. of Bio-Clean mixed with 2 gallons of water for every 500 gallons of tank capacity. It is always best to let the mixture stand for up to 45 minutes. Don't let it stand for more than an hour or the bacteria will start eating each other. Stir up the mixture and pour directly into the tank, cesspool or drains going into the tank. For best results on tanks large enough to require more than two pounds, divide the amount into two or three parts. Let a day or two elapse between applications.

** Note** Your septic system and drain field depend upon bacteria to keep them trouble free. If the bacteria are killed with chemicals the action STOPS and the trouble STARTS. Use only non-chlorinated, bio-degradable cleansers and washing compounds. Conservative and occasional use of bowl cleaners and bleaches is acceptable. Don not use automatic bowl cleaners that dispense with each flush.
