Spa 450 gallons, 99 degrees
CC 10 (just shocked)
PH 7.8
TA 50
CH 40
CYA not sure, ran out of test regent, ordered more....I changed the water 10 days ago, so not much if any.
Borates 50 (boric acid)
I am confused about the TA. Sometimes I read that it should be 50, others 100. What do you say?
Is a calcium hardness of 40 ok for a spa?
I ordered plenty of CYA test regent, what reading will allow me to switch to bleach? Fresh fill 10 days ago, I am using sodium dichloro s-triazinetrione as a sanitizer per bathing load and sodium dichlor once a week for shock.
