I am leaving for Hawaii in January.
I was going to shock my pool to 15 ppm to and see how long it lasts .
Its at 4 ppm free Chlorine now.
My CYA is at 50 .
I was on the automatic Frog system ,now I am off that system. I have been adding chlorine manually .
I have no way to add chlorine ( I am using bleach or liquid) automatically now while I am gone .
Bottom line I was wondering how much to put in for 10 days while I am gone to be safe or at least a guess ?
Before I go out and try my shock method of 15 ppm to see how long it lasts , I thought I would check on here for ideas.
