I am new to the pool scene and have a question.
Our pool builder put too much CYA (110 ppm) at the start up and we had trouble holding chlorine and the pool turned milky. We drained down to get the CYA down and to try to get the pool balanced.
I have not had the opportunity to get lab readings, but I did a few tests of our own.
CYA: ~50-45 ppm
Since the plaster is fairly new he said not to bother testing for Alk for over a year. I am skeptical. We have a blue stained plaster.
Our chlorine after refill was over over 20, but dropped to 15 ppm and has stayed there over a week with out additional chlorine (tab feeder is off). We have had 90 degree sunny days.
Every time I check I have to add about 2 cups of MA which I understand is common with 3 month old plaster.
I have a separate question about the Taylor ph test in the TF_100 kit. Does it have anything to neutralize the chlorine? Our other test kit does and maybe I haven't taken the time to find it in this kit.
Thank you in advance.
