    New pool owners, cloudy green water

    Bought an Intex 18' x 42" pool and the Intex CS8111 Salt water system. Filled the pool with well water and it was a cloudy green. I added 120# of pool salt 1.5 lbs of CYA and ran the filter for 24hours as recommended. Then I ran the "boost"/shock cycle for a total of 12 hours. Pool was still green and cloudy. I pulled the filter out and it was very brown, replaced it and ran the filter for another 12 hours. Checked levels and FC was low so I kicked off another boost.

    The water is still green but clearer now. It sounds like metals but just wanted to get everyone else's take on it. We are worried about staining of the liner from whatever it is. Assuming it is metal, it sounds like I can just get a sequesterant from a pool store, is that right?

    All I have are the crappy test strips (I know, I need to get a good test kit) but here are the current levels

    sodium choloride 2580
    total hardnes 200
    FC 2
    PH 8.4
    TA 240
    CYA 40

    Just added a couple of cups of ph minus before this test trying to get PH/TA down.

    Any help would be appreciated

    Yes, a sequestrant sounds like a good idea. If there are no metals, it will just sit there, bored. You might also have overpumped your well, which stirred up too much sediment and pumped it into the pool.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
