    Sparkly to Green in Hours (Pics)

    Faithful TFP'er here.

    Had a big storm last night. Due to some in-progress landscaping the rain water ran over exposed, recently raked, loose dirt plus some fertilizer-rich sod and into the pool.

    Searching previous posts the recommendation with dirt in the pool is to let it settle and vacuum but the DE filter only has push-pull handle so this is not an option plus the water is green.

    TF-100 as of 7pm last night, before storm:
    FC: 6
    CC: 0
    pH: 7.5
    Temp: 84

    Results from Sunday (7/12)
    cya: 40
    CH: 250
    TA: 100

    When the rain stopped I checked the pool and even with a flashlight knew all was not well. Normally I can see the bottom in the deep end with a flashlight as though looking through glass.

    About 2-3am this morning:
    Skimmed debris
    Backwashed to reduce water in pool.
    Recharged DE
    Added 12.5% chlorine to raise FC to 12
    Ran filter for an hour and shut off

    6:30am:
    Turned on pump
    Vacuumed dirt that had settled
    Added MA to drop FC from 7.5 to 7.2

    7:30am
    FC: 11
    CC: .5
    Added 12.5% chlorine to raise FC to 16
    Temp: 82

    8:30am:
    Backwashed and recharged filter

    9:30am:
    FC: 16
    CC: 0

    My plan is to continue SLAM unless anyone recommends otherwise. Open to any additional recommendations - and yes, I do realize POP will be needed

    I think you're on the right track - continue your SLAM. That's unfortunate about the rain run-off. That happened to another forum member yesterday as well. Good luck!

    Thanks Texas Splash!! I appreciate the confirmation and well-wishes.

    Just wanted to be sure and I thought fellow picture-hungry TFP'ers would enjoy the pics.

    A quick slam should have it clear in a short time.

    Not to hijack, but if FC levels were maintained properly, how could this happen?

    Edit:
    Is it because of the volume of organics added to the pool overwhelmed the FC, reducing it to 0 in a short amount of time?

    Hi Dom,

    The FC was not reduced to 0; in fact I have no reason to believe it dropped below minimum FC levels.

    So far there has been no loss of FC since raising it to shock level this morning.

    There has been a lot of dirt in the backwash water the 2 times it's been backwashed today.

    If your FC didn't drop then vacuuming and filtering should very quickly clear the pool and a full SLAM may not be required. However if organic matter is left in there for any length of time you will see the FC drop.

    That's perplexing, theoretically it should have been impossible for algae to bloom.

    That may not even be algae.

    Progress, incl. pics

    2:30pm
    FC: 15
    CC: 0

    Pool normally looses 1.2 to 2 ppm FC per day. Despite the color this morning nothing indicates an algae bloom, just dirt. Have backwashed and vacuumed again.

    Overall:
