Upon fresh fill these are my readings:
TA: 60ppm (target 90ppm)
PH: 7.0ppm (target 7.6ppm)
I am going to leave CH alone but was wondering if I should raise PH first (sodium carbonate)? I know this will also raise TA and then I could adjust TA as necessary. Or should I raise TA first with Sodium Hydrogen Carbonate and then see where the PH is?
