I've been battling this problem for a few months and pool stores haven't help much and Summer is here. According to my Taylor Kit (K-1003) CC 10, pH 7.2, TA -170 as of today. My water is still light green I've treated for algae, slam it and I just been putting too much $ that I'm just giving up. What do you think "Drain It". Thanks firstname.lastname@example.org And of course Leslies readings are always different.
