We had a build up of CYA and drained and refilled 70% of our pool water. We restarted our pump (Pentair Intelliflo Variable Speed, Pentair Quad D.E. Filter) Came on fine.
But our Ozonator Paramount Clear O3 is not producing bubbles. The power to the unit is on, the light is on. Worked fine before. Have turned the needle adjustment all the way up and no bubbles still.
Thanks for your help,
