    Went out to work on the pool this morning. It's clear but has a green tint to it. I have added well water the last couple of days, but water was greenish before.

    Cl 5.5
    pH 7.8
    Alk 220
    CYA lower than 30 but there is some CYA (when tested at 30 the water was cloudy but could still see the dot)

    Adding more CYA now. What can I do to get rid of the green tint?

    If you've got dichlor, don't add CYA -- add dichlor! For each 1 ppm of FC with dichlor, you'll get 0.9 ppm stabilizer.

    But, with that Alk, lower your pH to 7.0 - 7.2. Muriatic acid is best -- see the linked safety page in my signature.

    Is there a way to lower the alkalinity?
