So FC was 4 at 630 this morning, I added 4 more gallons of bleach, restested just now FC 10....I have to get it to 16...gah! More bleach I guess...it should take 32 drops to get the test sample clear for FC of 16, right?
If you are using the standard 10 ML water sample size - yes.t should take 32 drops to get the test sample clear for FC of 16, right?
