    Step by step for salt pool refill

    Hey guys, First post...

    I am having to drain and refill my above ground pool for various reasons (water is full of iron, want to relevel sand bottom, want to paint the rails)...anyway, I'm looking for very detailed step by step instructions for refilling and basically building the water from scratch. Things I add the salt after pH and alkalinity are right? Thanks!!

    Welcome to TFP! Good to have you here

    Day 1
    For me, it's pH first
    Then a small amount of chlorine to stop anything from starting to grow, say 2 ppm
    Then CYA to protect the chlorine, 30-50 ppm

    Day 2
    Assume CYA level is at your target, and add the right amount of chlorine per FC/CYA Chart
    Adjust pH if need be

    Day 3
    Check TA & CH, but don't do anything about either
    Adjust pH
    Top up chlorine
    Add salt
    Report all your numbers here to let us know. If anything's untoward, we'll let you know

    Day 4
    Adjust pH
    Top up chlorine
    Turn salt cell on at your best guess level

    Then test pH and FC every day for a few days to see if the SWG is keeping up; adjust it as needed

    Within the first week or so, do an overnight chlorine loss test to rule out any algae carrying over from before the fill Overnight Chlorine Loss Test
    Then raise your CYA to 70-80 ppm (correct level for a salt water pool)

    When you can, set up a signature - see Pool School - Getting Started - which will help you get the best possible advice.

    Also, read these (they're all short) and it will all start to come together.
