i hope i'm not too late to add to this thread. so it seemed that while my chlorine use was high, it was possibly within the range of normal. the issue was that my FC levels should be between 7-9ppm for my cya of 60 and never drop less than 5 and adding 1 gallon of 12% chlorine, i kept losing at or below 5 by evening (i started at about 10 after adding a gallon). so i figured i'd just have to add 1.5 gallons one day to get it to more like 13ppm so by evening it was 7ppm.
I did this last sunday morning - put in 1.5 gallons of chlorine (and over an $8 cost) and by evening, to my frustration, it was at 4.5 again!
i thought i was losing my mind. So monday morning i figured i'd try again. Same thing happened! so instead of using 5-6ppm, i was using like 7.5 ppm.
1) Does this make sense? this would cost me $1k+ in chlorine for the season or 10 times what i used when using tabs!! i threw in the towel and monday night put in tabs. for the first time this season my chlorine test comes in at 7-7.5ppm at all times - morning and evening.
2) according to everything i read if i continue to use tabs my cya will go up. but for years i used tabs before i knew anything about the science i learned on this website. i used a regular pool test strip for years and the cya color was always in the "ideal" range box of 30-50ppm. i used tabs the whole season and never saw it moved from that color. why?
