5,061 gallons.
Re: Cannot raise CYA
After seeing your volume, I remember doing this before somewhere up in this long thread. In a 5061 gallon pool, each quart of 8.25% bleach will add about 4ppm of chlorine. Each cup will add 1ppm. Use those as a reference to figure out how much bleach you should add to get to shock level which is based on your CYA. http://pool9.net/cl-cya/
Re: Cannot raise CYA
Based on my CYA level chart says I need to take it to 20ppm so 5 quarts of bleach should do it, right? Do I run the pump while pouring in and how long should I run the pump after? Thanks @watermom.

Re: Cannot raise CYA
To shock you need to keep your FC level at least 30% of your CYA reading. That is... At a reading of 70 cya, your minimum shock level would be 21FC. Run your pump 24/7 and turn off your SWG. Keep the shock level up until you do not loose more than 1 FC overnight. Then, you can turn back on your SWG and reset your pump timer.
Based on your prior postings, your cya level is likely much higher than 70. It's just not yet showing up in the test. So, retest and adjust accordingly.

Re: Cannot raise CYA
Always have your pump running when you add chlorine!
Re: Cannot raise CYA
Thanks! Will be testing and shocking tonight. An interesting side note, my pool is crystal clear, can see bottom of the opposite side of the pool in detail. Water looks great. Shocking it won't hurt right?

Absolutely not!
(Unless you have metals-contaminated water.)
