No Chlorine?

[MartyW]

I don't know if this has any bearing, but I never opened the pool last year. We were out of town part of the summer and also had some remodeling done. I don't know what the cya was 2 years ago. If what you are saying is continue to shock, how much chlorine would I need? The water looks great, clear and sparkling - just no chlorine. By the way, I'm a guy. Thanks, Marty

With a CYA of 60, shock level is 20 ppm, and you need to sustain that as consistently as possible until you can go overnight without losing more than 1 ppm of chlorine. I don't know how much total that will be, but

I've looked at the best guess chart. I'm still at a loss as to how much shock I need to put in to reach the desired level.

In your pool, each quart of 6% bleach will add a little under 1ppm of chlorine. So, when you test your chlorine level, use that as a reference to know how much bleach to add to take your chlorine level back up to 20ppm.

Boy, that was helpful, huh Internet went out in the middle of editing that post. Thanks, Watermom, for finishing it for me!
