Crystal clear water but all figures a bit off.

[Guido]

Hi everybody just starting with my first season with my, last fall finished, 22K IG plaster pool. Cartridge filter and SWG. We opened 6 weeks ago and the water went from very cloudy with in 1 week to crystal clear. With the SWG came the first set of Salt which I added after the temperature stayed at around 64. The builder added balancing packs into the pool to get my CYA and TA up and I’m constantly adding acid to keep the PH down. My TC was at around 6 with the SWG setting at 20%. Last night when I started the pump I switched without noticing it the SWG to boost and was running 18 hours. (Just got back from work).

Here are my figures from today. Measured with Taylor kit. (PS234s ordered)

Temp water=71
Temp outside=74
CYA=70
TC=15
FC=15
PH=7.3
TA=150

Beside the ph everything looks to me off scale but my water is crystal clear.
What should I do from here? I tried to find similar posts here but I was not able to.

Any hint were to look or what to do is highly appreciated.
