    I can think of no reason why you want to force your chlorine down. It will come down on it's own somewhere about 2ppm daily. Why do you feel you have to reduce it?

    Those numbers aren't right.

    the FC should be 8, not 0. if CL is 8 and FC is 0, your pool should not be clear.

    CYA is cyanuric acid, so you can't have a reading of 40 for CYA and 20 for cyanuric acid.

    The pH is low. It should be between 7.2-7.6.

    You should run those tests again before adding anything else.
