I took a pH and FC sample, had almost no chlorine and about 7.8 to 8 pH. I added 2 gals of bleach. I took a reading 6 hrs later and the FC was up to about 4.
Today I took another reading, and the FC is close to 1. I took the CYA,, and it is about 26 (according to the black dot test).
According to the poolmath calculator, I need to add about 106 ounces liquid CYA and 1.5 bottles of bleach. Does it matter in which order and does one have to sit before adding the other?
Thanks in advance
