    The overnight chlorine test gives a good indication of the cause of chlorine demand. Sunlight always consumes chlorine during the day. Over night, chlorine is only consumed cleaning up the water.

    The process:
    Test for FC and CC in the evening after the sun is off the pool. Be sure that and chlorine you've added has had a chance to disperse throughout the pool.
    Test for FC and CC again in the morning before the sun is on the pool.
    The clean up is done when you lose less than 1 ppm FC overnight and there's 0.5 ppm or less CC.

    When the chlorine holds overnight, I'd start to bring up the CYA to the target level. Adjust pH and CH as needed.

    As I understand, SWCG's don't work when the water's cold. Do you have a owner's manual for it?

    What are your FC, CC, TA, and pH readings now

    So I finally did the overnight thing and I'm not losing any chlorine. Ph is around 7.6-7.8. TA is 120. I've turned off the SWCG due to cold water at the moment. I'm thinking to bring up cya a bit and maybe a bit of baking soda?

    Thanks for all the help. I do have one more question, what i the best way to increase calcium hardness? Mine reads around 140 and from reading this forum I see that for concrete pools (which mine is) its recommended to be above 200, but I have not been able to find the best product to use.

    You can chlorinate with cal-hypo for awhile and that will increase your calcium at the same time as adding chlorine. When you get your calcium hardness level where you want it, switch back to bleach.
