Pool Survived Vacation! ?? Chlorine levels

[BigDave]

I'm so happy your pool was still clean when you got home. One-up for your son for getting it done!

Watermom is absolutely right: FC of 5ppm is good, you need to test and adjust your dose daily (the 3 Cups a day way just for your son), and you probably want to move your CYA up.

I was testing in morning past few days. Today I will test around 5:30pm today and add bleach accordingly to raise to between 4ppm and 5 ppm. This may NOT be 3 cups, right?
I think I should test CYA again before I start adding dichlor to bring it up..Is that right also?
Pool looks great. I wish the weather did too...Perhaps by Friday.........

I think you'd be better off aiming for 7ppm like Watermom said - then work your way back down if you end up with more than 5ppm each night. The goal is to be sure to stay above 3ppm FC all the time.
You're right, do test CYA when you get a chance then figure out how to raise it.

OK will let you know what happens in a day or two. THANKS

Yesterday FC said 2 and CC 8 which did NOT make sense. Put in 3 ounces of dichlor to raise CYA as suggested.
This morning with basic test clorine was way over 3 and then this evening FC 4 CC.5 and did CYA test which read about 55. So I put in 3 cups bleach. So now I'll stay with bleach right??
Thanks

Sorry for not checking in - I was completely (almost) offline - camping with WEBELOS.
Yep, with a CYA of 50ppm to 60ppm you are good. I think you should be adjusting bleach dose to maintain an evening FC of at least 5ppm (test before adding bleach). Let's call the FC 2 / CC 8 test anomalous, but do keep an eye on CC.
