    Re: low salt reading and low chlorine

    Hi, and welcome to TFP!

    What are you using to test your water? To assist you, we really need a full set of numbers from a good test kit (not strips)

    Salt (you can use strips for this!)

    12-40# bags of salt should have raised your salt level by 4313ppm! What are you using to test your salt level??

    Shocking is not a one-time event, it is a process. I suspect you are unable to keep chlorine in your pool because something organic is busy eating it up! (Also, with low CYA or stabilizer, your chlorine will burn off in the sun on a daily basis.)

    Shock your pool at night, and keep your FC level up until
    1) you have no FC loss overnight, and
    2) your cc's are <0.5ppm

    "Shock" is a process, not a product!

    Welcome to TFP!!

    Which salt unit do you have? (I only have experience with the Goldline/ Hayward units, but others here may have the same unit you have and be able to tell you how to 'recalibrate' the unit --- you should have a LOT more than 900 ppm salt in the pool)

    As long as the unit isn't generating, use bleach to sanitize the water

    The more info we have about your pool, the better we can help 8)
