    Can you SuperChlorinate while adding CYA?

    My water was tested yesterday and my CYA level was 10, and the water temperature was 70. Today was a bright sunny day and my SWG was operating at 30 percent. Water temp. is 83. I added 900g of CYA through a skimmer sock about an hour ago. Can I super chlorinate overnight?

    If you mean superchlorinate with liquid chlorine yes. We don't recommend using the "superchlorinate" feature built into SWGs as it can shorten the life of the cell.
    superchlorinating (shocking) and adding CYA have no effect on one another.
