Have an above ground pool 3,754 gal. Ph was 7.5, Ta was about 140, Cya was 100, and hardly any chlorine. Is the only remedy to drain at least half of the water,and refill?? Here in Arizona we have about 2 more months of HOT weather left. at the end of October i will drain it all and put it away till spring. Is it safe to swim in if i leave it alone? or does it need attention right now? I am new here, Thank you for your time, and help, Harold.
