Pool Survived Vacation! ?? Chlorine levels

[mroll]

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

[mroll]

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.

[B]OMG..Cannot keep chlorine level up!!!Yesterday in evening FC was 2 so put in 4 cups of bleach..[/B]This morning (after tremendous rains last night)FC was .5!!!! I have gallon of shock from Leslies. I want to put in half of it. WHAT do you think??? Where is my chlorine going???

[BigDave]

That's probably too much. Try 4Cups (1qt). and lets see where that moves your FC, CC and pH. What is your pH now, after the rain?

[mroll]

PH 7.3..Just added 4 cups shock..When should I test again? tonight right?

[BigDave]

Can you test about an hour after adding the liquid chlorine? Let's see where that moves the FC, CC and pH.
