when doing the alkalinity test, i do it like normal, 25 ml mark, 2 drops of 7, swirl, 5 drops of 8, swirl and then 9 and swirl till turns red, but instead red at 13-14 drops turns light organge and stays there, i can put 10 more drops in, wont make dif, also maybe worth noting, when turns green not very dark green like in videos, ph is 7.6 but FC is very high due to shocking recently since had to partly drain and refill due to CYA being rly high, CYA is down to about 55 now, might do slight drain to get it to 40-45, but anyways any idea whats up with alkalinity test?
alkalinity turns light orange instead of red

High FC shifts the colors from green>pink to blue> yellow or some shade in between. I'd say you have 140 TA.
ok thanks, atm, would best bet be to wait till get CYA a little lower and FC to level on CYA/FC chart, then test and worry about alkalinity then? and is cya level of 50-55 fine if chlorine doesnt bother us much and going be in 90 or higher with water temp prob closer to 80 due to solar panels?
55 CYA would set your minimum at 4 and your target at 7-9 which is well below the threshold to test/adjust pH. TA will come down on its own if you keep pH between 7.2>7.8
and its my understanding from what i read that free chlorine of 7-9 with cya at 55 wouldnt be as strong or hard on person as fc of 7-9 if cya is at 30, is that correct, and by as strong mean wont be as likely to irritate skin or burn eyes if was at same level with a low cya, is that correct?
