no mystery here. you’re adding 5.4 ppm. your fc burn off is at least 3ppm/ day, probably more with your low cya.
i would increase your cya in the 50-60 range and dose everyday while it’s hot...
you’ll want your target fc in the 6-9 ppm range and never below 4-5ppm

i guess i forgot your original question. there’s a chart around here showing that the higher concentrations (10%) do go way down in a few months stored that way. i keep mine in a conditioned space (closet) until i use them

Also check the Julian date code on the bottle and make sure it is fresh. Even stored in a hot garage fresh chlorine will hold potency for at least a week or so. How much do you buy and store at a time?

I have been adding cya to the pool have not re tested it yet... I usually buy a case 4 gallons at a time... I found a spot that I can store in inside away from everything that should solve that problem. guess I need to stay on top of the chlorine a little better than I have been
