My CYA is about 50 and I’m gradually raising it up. We had people over yesterday afternoon and now my FC has dropped to 2.5. The pool math app is telling me to run my swg at 2% and run it for 100 hours to get back to 3.5 ppm. The app has my swg correct as a Jandy aquapure 1400 and my Pool size as 15k gallons. Do I have something set up incorrectly elsewhere in the app?
