It sounds like you are making progress! Keep your chlorine at shock level and run your pump 24/7 while you are working to clear it.

On a 17K pool, 2 gallons of 8.25% bleach will only add about 9.7ppm of chlorine, not 20. Were they gallons? Most bleach is sold in 121-oz. jugs which is more like 0.95 gallons. If that is what you used, it would have added about 9.2 gallons. (For future reference and to help you figure out doses, in 17K gallons, each quart of 8.25% bleach will add 1.2ppm and one of the 121-oz jugs will add about 4.6ppm.)

(By the way, no need to use the 'report post' button to alert us to see a post. Especially at 1:49 a.m.! We will definitely see it when we come back online. Thanks.)
