With CYA now at 50 ppm, CL is dropping from 5-3 over 24 hour period. This requires 40 oz bleach a day or 2gals and 24 oz a week. I am planning on raising it to 60 ppm to see if that further reduces the chlorine need. At that point I will not raise it any higher.

Add 8 oz a day of muriatic acid to keep the pH at 7.3-7.4 for iron stain control.

Will advise on results.
