I have an apex and am currently dosing my calcium during the day from 12 to 6/four minutes per hour and my alkalinity at night from midnight to 6 AM/two minutes per hour. I'm trying to raise my alkalinity up from a stable 8.3 and was considering dosing both part a and B, Randy's recipe back to back/eight minutes per hour during the day, is this better or should I leave things as they are?
