So we've had a boatload of rain here the last few days - I have had to empty water out of the pool several times to keep it from going above the skimmers. Chlorine this morning is <1.0 ppm and pH is around 7.8. Clearly I need to add bleach, but how much? And what to do about the pH at this point? I did not test the TA as I am running a tad late this morning.

1 gallon of 6% bleach adds 6 ppm FC to 10,000 gallons. Calculate that out for your volume. Don't worry about the pH. It's still in range and may drift down again. What's your CYA these days?

CYA = 90
TA = 140

I've not added any pucks, so there should be nothing adding CYA anymore. I added 3 jugs of 6% 96oz chlorine. And removed 7-8 frogs or parts of frogs from the skimmers.

I'll retest in the morning and if need be can add another jug. Should be swimmable by afternoon I would think.

You've got to keep your chlorine level up between 5-10 all the time or you're going to have algae! Test your pool this evening after the sun is off the pool and then in the morning within two hours of sunrise. Note how much chlorine you lose overnight and post the results here. Did you get your K-2006 yet? If you did, also test your CC reading in the morning and report that, too.
