    I'm not aware of any reason not to start right now!

    There is no reason to wait. Attack the algae in the dark

    I would go for it... As it gets dark you wont have to worry about the sunlight using up any of your chlorine...

    Do it! Jugs away now, and again just before bed. And then hit it again before you leave for work in the morning.

    Re: slamming in the evening?

    From 0ppm I dumped in 3gal of chlorine expecting it to get to 16ppm but when I tested I'm getting a whopping 27ppm. I only waited maybe 15 or 20 mins after before testing. Did I not wait long enough?

    Re: slamming in the evening?

    What is the strength of your bleach? How sure are you of the pool size?

    You may not have waited long enough ... circulate at least 30 minutes.

    Re: slamming in the evening?

    Yes, it should come down pretty quick. Are you using PoolMath to calculate your amounts?

    0 to 27ppm FC in 20k gallons takes 672oz of 10%. Which is 5.25gal. Something is off.

    In using an android app called pool pal for logging and calculation. Has always been spot on for regular calculation. It said to add 373oz which is about 2.9gal

    Re: slamming in the evening?

    Usually 20 minutes is good, it's the minimum. I usually recommend 30 minutes just to be sure. In your case if you were at the short end of 15 minutes maybe it wasn't mixed and that's why you tested at 27. As Pooldv pointed out the math isn't adding up.
    20K and 10% the three gallons should have given you about 16 ?? If it really was 27 did a lot of algae killin' overnight

    Re: slamming in the evening?

    So today would be day 4 of slamming. Last night I raised my fc to 16 late in the afternoon. Tested before leaving for work and my fc was 15.5. Does that mean I've passed the overnight test and can stop?

    Re: slamming in the evening?

    I never had a problem with the water not being clear . I can see the slightest speck of dirt at the bottom of the floor. I'll be home in a little bit I'll test and report
