Hello TFP! Built a new pool and spa last March, 2018. Pool is about 12,300 gallons, chlorine system.
List of equipment:

  • Filter: Jandy 460 CART Filter
  • Pump: Jandy 2.0 Variable speed
  • Computer Center: PDA PS6 (pool/spa)
  • Jandy PDA controller
  • Aqualink Connectivity
  • Heater: Jandy JXI400 Natural Gas Heater
  • Cleaning System: Polaris 3900 Complete with booster pump
  • 4 LED lights
  • AquaStar Automatic Chlorinator
Pool plumbing and finish:

  • 2 Skimmers
  • 5 returns
  • 2 Safety main drains
  • Pebble pool finish (dark)
Water features:

  • Two 18” waterfalls
  • Spa spills into pool
Most recent chemistry:

  • FC: 2.0
  • CC: 0
  • pH: 7.7 (having to add ~10 oz of muriatic acid daily to keep it in check)
  • TA: 80
  • CYA: 40
  • CH: 400 (concerned about this high number)
  • Borate: 80

Regarding the pH creeping up on me between 0.10-0.15 per day, could this be due to the new plaster still curing?
CH mysteriously creeped up from 350 to 400 in about a month. I have not been using shock at all. Maybe due to the new plaster and normal evaporation?

Any thoughts or recommendations will be much appreciated!
