    Could you post a full set of water test results and describe how your water looks?

    Are you using test strips? If so, you may have so much FC that it's bleaching out the colors! On the other hand, if the pool is green and thick enough to walk upon the surface, what you describe would not be surprising.

    We really need more information.

    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!
