Team,

My CYA is around 40 constant.....how do I get it to 70 to 80? I know buy some "conditioner" and put it in a sock by the return. My question is how much will get me to 80 if I am at a 40, now? This Texas heat is eating the bleach/chlorine.....how much do I add. 18,500 gallon AG...

Many thanks in advance..

Charles

In your pool, every 1.5 lbs. will add about 10ppm of CYA.
