Reading today after adding some CH. I added 4lb 6oz of CH and this should have added 20 points to the reading according to the instructions on the pack.
CYA <35 (that is lowest the test shows)
FC=3.5
CC=0.5
pH=7.6
TA=70
CH=125
CSI = -0.48
Temperature was 79.
So the CH is slightly higher than I expected, but then my estimate of 17,000 gallons for the pool maybe incorrect.
So today I will be adding CYA, Chlorine, and CH.
Note all the amounts below are rounded as I work in metric.
CYA I will be adding 23oz
CH I will be adding 4lbs 6oz
Chlorine I will be adding 8.5 fl oz
I will also track some some Dry Acid to work on the lowering the pH if I have to.
Do I need to worry about adding these chemicals at the same time, or should I separate the timing of adding these?
