    Everything looks fine except the FC! Get some bleach/liquid chlorine in there!

    Have you found the PoolCalculator yet? Link in my sig.

    With the 40 CYA, keep FC between 3 and 7, and never below 3.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    oh!

    Using the small spoon shaped end of the dipper, add one heaping dipper, or two level dippers, of R-0870 and swirl to mix. If the sample turns pink for a moment and then turns clear again, or if it turns brown, add another dipper of R-0870. If the sample remains clear the entire time, your FC level is probably zero, however it is best to verify that with an OTO chlorine test, since the FAS-DPD test is prone to the occasional false zero.
    Use the OTO/yellow drop test. It is a bulletproof test for the presence of chlorine.

    Walmart, Home Depot, Lowes.. Pretty much anywhere, anytime it has two bottles (usually) and is normally labeled pool test it or something like that.
