I am using the PoolMath app, but I can't tell what to do as the recommendations for TA and pH are opposite.
For alkalinity, my test kit measured 150ppm, and using the formula (pH=7.3; CYA=80) I get carbonate alkalinity is 126.8. [Should I be using this as my reported alkalinity in the app?]
The problem is that the recommended (ideal) alkalinity is 50-90 (60-80), so I'm at least 40ppm higher than recommended.
However, my pH is at 7.3 (crept up from 7.1 over the last week), which is within the recommended range (7.2-8.0) but not ideal (7.6-7.8).
For lowering the alkalinity, the app suggests I "reduce pH to 7.0-7.2 with acid and then aerate to increase pH"
But it also suggests raising the pH by using washing soda/borax (20 mule).
What should I do? Thanks in advance!
All measurements: (FC=6.5; CC=0.5; pH=7.3; TA=127; CH=425; CYA=80; SALT=3,790; TEMP=84f; CSI=-0.15)
