1/2 to a gallon for each of my 40 gallon black and gray tanks. 1-2 cups for my 40 gallon fresh water tank.
How much clorox do you add per gallon of water for the fresh water tank
and for the black tank? Tanks on my rv are 13 gallons for the black
tank and 25 gallons for the fresh water tank.
Thanks,
TONY
