1 US gallon = 4 US quarts = 8 US pints = 8 X 16 US fluid ounces
1/2 US cup = 4 US fluid oz

SO
1/2 cup per gall is
4 in 8X16

OR
1 in 2X16 thats 1:32 by volume
That seems like a 3% solution to me.

But what do I know?

Yea, 3% bleach, which is maybe 6% sodium hypochlorite, which has about 50%
chlorine. So multiply 3% by 3% and you'll come up with about 0.1% chlorine
solution.

Gentlemen, you have missed Peggy's point. Commercially avaliable bleach
solution is 5-7% Sodium hypochlorite solution.

Cheers

I thought they were going for the ratio of chlorine/water after the
bleach is mixed with water...the amount of chlorine that actually ends
up in the tank. Iow, if you chose not to use bleach, but undiluted
chlorine...
