I have the app and read through the pool school, but I want to be sure. I seem to have a hard time determining the color of the 7.8 ph vs 7.5. I haven’t reinstalled the salt cell, so I’m using liquid chlorine. I have a fiberglass 14,500 gallon pool btw!

PH- 7.8
TA- 80
CH- 275
CYA- followed directions to a T and filled whole tube and still saw the black dot. So under 20?
