Ran the tests two days in a row and pretty much got the same readings both days:
PH: 8
Free Cl: 0.5 ppm
Comb Cl: 0.5 ppm
TA: 190 ppm
Cal Hardness: 130 ppm
CYA: Now this one I'm not sure about. Is it when the black dot turns gray, or disappears altogether? Because it never disappeared with the tube filled up all the way to the top. It went gray around 50 ppm.

The circular calculator says Saturation is 0.5

So, PH and TA are high, and Calcium Hardness is low. I need to add acid and calcium chloride, right?
I put in about one third gallon regular Clorox bleach last night because I could'nt get a free chlorine reading at all yesterday.

My best guess using the Pentair pool volume calculator is 15,000 gallons not counting the 7' diameter jacuzzi off to the side. The pool shape is kind of weird so it's a rough guesstimate.

I'm open to whatever suggestions you have for me.
