I tested for the first time at home on 4/18 and got these results:
FC - 6.8
PH - 7.7
TA - 90
CH - 160
CYA - messed this up but I know it was very low, if existent.
Added half a bottle of acid then tested again on 4/22:
FC - 7
PH - 7.7
TA - 110
CYA - still low or at 0
I had my "ah ha" moment after this test when I realized that the constant acid demand was due to 0 CYA. I added a gallon of liquid CYA around 4pm on 4/23 and ran the pump for 24 hours.
Last night I tested again with some odd results:
FC - 12
PH - 7.7
TA - 90
CYA - 50 (finally clear on this test)
Couple of qs. Is this even accurate or should I wait a few more days from the CYA add? Is the high FC from running the pump 24 hours? I know I still need more CYA, especially since I think it was at 0. Is it too soon to add the second gallon? Also is it ok to be in the pool with this high FC?
