Your pool and water look nice!
I'm still a little concerned about the low chlorine level today after adding quite a bit last night. So, let's do one more thing to make sure there is nothing going on other than chlorine loss to the sun due to low CYA. (Which will soon be coming up with the addition of your dichlor.)

Go ahead and test this evening after the sun is off the pool. Add enough chlorine to take your chlorine level up to around 6 or 7ppm. An hour later, test your chlorine with your K2006. Then, in the morning, within an hour of sunrise, test again (FC and CC). If you lose no more than 1ppm of FC overnight from sundown to sunrise and have no higher than 0.5CC, then we'll know that you don't have a chlorine demand from something going on in your water.

Also, retest your pH in the morning and report that level also.

(How come nobody is swimming in that pretty pool! At least where I live, today is a great pool day! )

Will add 2.5-3 gallons of bleach and wait an hour then test.
One of my Daughters had my 2 labs in it an hour ago, I just got in and cleaned it...Pool is really clean. Sure would be nice to have it like this all summer.

Will test and report back.

Thanks

CC of 1 is not good. That right there tells us why you are using so much chlorine. You are definitely fighting something in the water. (Assuming that is not an error.) With that CC reading, I think it is very likely that you will lose more than 1ppm of chlorine overnight. If that is the case, you need to keep the chlorine high until you can pass the overnight test. Post your FC, CC and pH in the morning.

Tested before the sun came up on the pool....
fc 11.5
cc 0
ph 7.7

do I keep pouring the bleach in and keep it high or use other products. i have not added any more dichlor just bleach

thanks

Glad to see CC of 0 but since you lost more than 1ppm of chlorine overnight, you need to continue to keep your chlorine levels up. Keep using bleach. Do the overnight test again tonight and post your results in the morning.

By the way, it is ok to swim. You just might want to wear old swimsuits. Chlorine at this level won't hurt you but it might be a little hard on your suit.

Nothing added tonight. No sun on pool
