Hello,
I have a 900 gallon vinyl AGP - new set up.
I added water, bleach, and CYA.
Pump on for 48 hours, and the CYA is 40 with FC of 4. Excellent.
I added borax and muriatic acid.
Pump on for 48 hours, and the borates are 50 with a pH of 8.0. TA was 110-120.
So I added 8 liquid ounces from a measuring cup of 31.45% muriatic acid.
Pump on for 48 hours and retest. TA is still 110-120 with pH of 7.4
I'm using HDX brand 5-way drop test. I know it can be hard to discern the shades of yellow for FC, but it was immediately available to at least get the pool started.
Since the pH came down, it makes me think the acid did something.
Could the acid be old or could the test be way off for TA - or something else?
