    my pool is green with fresh fill

    I have a 4ft x 20ft intex style pool with a salt water filter. I just filled it, no well water, and its clear but has a slight green tint to it. I went to the local pool store and he had me put 2 bags of shock in it. Nothing has changed. Was wondering what else I could try.
    Thank you in advance for any help!!

    I'm assuming it's crystal clear, but some shade of Emerald Green? Odds are, it will go away in a day or two unless you filled from a well or a pond or something other than a municipal water supply. It's probably some rusty water that looks pale yellow normally, but against the bluish pool, looks green.

    If you just go ahead and balance it as if it weren't green, it should disappear. It's a common problem. Check the search function and see for yourself.

    And now, let's address the pool store advice. Did they perform a free water test? Did their expensive "shock" do anything? Odds are yes and no, respectively. Let that be a lesson.

    My immediate suggestion is to relax and see what happens to the tint. While you're waiting, peruse Pool School, especially the ABCs, Test Kits, Recommended Chemicals, Poolmath, and Water Balance for saltwater pools. If it's not too late, hold off on the salt until you get things straightened out and hold "Diamond Day" Post 5

    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!
