    Help Yellow Water

    Hi,

    So my pool water just had RO completed. Water was balance perfect with stabilizer added. Now we had a huge rain storm in San Diego area and my water is yellow from the soil runoff. What do I do to get back?

    Thanks for the help!

    Unfortunately a whole lot of filtering, brushing and patience. Letting it settle then a very slow vacuum may help hasten the process.

    Is it cloudy yellow or is it clear yellow? I assume its just dirty and not that iron or something else was introduced, but others can help if that is anticipated. Good luck.

    Good news there is no dirt. Just clear yellow water like urine.

    Can't be of much assistance without test results from a recommended test kit.

    Usually it's a SLAM procedure that's on the menu.

    Got a pic? I doubt that is from soil runoff. Assuming it's not, test results are needed.

    I'd be interested in the pH and if you've added any acid just prior to this.

    So my water was crystal clear and balance yesterday until last nights major storm which we had over 2 inches or rain and we live on hill so water goes from one neighbor to the next.

    Numbers:

    FC 2.5, I going to add 2 quarts of liquid chlorine.
    CC .5
    TC 3
    CH 425
    TA 110
    CYA 40
    PH 7.8, I going to add 2 cups

    Thanks for the help.

    Sounds like a plan. Could be runoff (it would be awful to discover the upstream neighbor just applied Iron Sulfate to his roses!) or there could already be Iron in the water and the aeration from the rain raised pH enough to cause it to precipitate. Adjust pH, raise FC, and run the filter and see what happens.

    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!

    Lower or raise PH?

    Thanks for your input! The pool was perfect with no metals and completed the RO prior.

    Very frustrating!
