To keep your holding tanks looking clean and smelling fresh, use the Flow Max holding tank treatment regularly. For grey tanks, pour two ounces of RV tank treatment into the tank and take a drive to slosh around the solution. Drain it, then rinse using a flush valve. For black tanks, pour two ounces of this treatment into your toilet bowl with one gallon of water. Flush the toilet and let the treatment sit. Be sure to store all bottles between 50°F (10°C) and 105°F (40°C). Please note: Temperatures above 85°F (29°C) will not require additional treatment. Temperatures below prolonged 40°F (4°C) may require additional treatment. Holding tanks should be emptied weekly.
