Hi all, I haven't been to my CPO class yet, so when I noticed that my automated chemtrol feeders were adding endlessly and the pH and ORP weren't changing, i tested the alkilinity and found it was too high. i added HCl and now the alkalinity has stabilized but the feeders still won't change the pH or ORP. this has happened with both the spa and the lap pool which is 20' by 8' (roughly 18,000 gallons). both pools had high alkalinity and i'm fairly certain i added too much acid. but the spa water still has a green tinge and last night somebody was in it without my knowledge, they reported skin irritation and their swim trunks went from blue to grey. i get a smell of chlorine around the spa. the lap pool is completely clear now but the feeders still wont change the levels. does anyone know what i may have done and how i can fix it?
