    Used my new big Taylors test kit with salt kit as well today and came up with the following:

    Fc = 7.6
    Cc = 0
    Ph = 7.5
    Ta = 90
    Ch = 540 ppm
    Cya = 100 ppm

    Salt = 4200 ppm

    Hows it look? My swg is only on 20% maybe 40%. Running 9 hrs a day on a 1hp 1.5" 13500 gal with DE.

    SWG is a jandy apure35plg.

    My thoughts is calcium is a bit high and cya...a 1/4 drain and fill in the future may be called for...

    Looks like you have a good understanding.
    Do you know the CH of your fill water?
    Don't be surprised if you have to drain more than 1/4th of the water to get the CYA down.

    I would lower your CYA level. Ideally you want it in the 70-80 ppm range. What is the CH of your fill water ?

    Everything else looks good ! Nice job !
