    salt water gen.?

    I am getting fc readings consistently of 2ppm with cc-0. My cya is around 65-70. My fc is not dropping but why is it so low? It is running at 100% and my salt level is at optimum.

    Try performing the overnight fc loss test to rule out organics.

    How many hours per day are you running the pump?
    Which zodiac cell do you own? 25k, 35k or the 45K?

    I know... you stated that in the initial post Turn the SWG off in the evening, measure FC and the remeasure FC before the sun comes up. If you lose less than 1ppm overnight you can rule out organics.

    In the mean time you should raise your FC to 3-4ppm using liquid chlorine.

    After you rule out organics with the Overnight Free chlorine loss test, then here are some other things to test.

    Be sure the salt cell is clean. If you see calcium build up inside the cell, then clean per the manufacturers instructions.
    If you are running the pump 24/7 with a 25K cell, then you may need to supplement the Zodiac with some liquid chlorine (regular 6% bleach).
    1 gallon in a 20,000 gal pool should increase the FC from 2 to 5 and the Zodiac should be able to maintain that level unless you have a heavy bathing load.
