    Algae I.D. help and ?'s

    Hey Y'all , been paying attention to the forums for quite sometime but never needed help , now i need the forums advice . My pool has had quite a rough week .Big pool party saturday into sunday ( it was a good one ) Lots of kids all week and temps above 95 too . I run it for 12 hours at night since i get a discount on the electricity . Noticed Sunday evening the water was clouding up so I tested it and came up with normal #'s except for the fc 1.5 ( usually 3-3.5) and cc which was a little greater than .5 but less than 1.0 (using the 10ml ) So i shocked with 2 lbs of cal hypo and increased the output of the salt cell to 60 and have run the filter nonstop since .

    Todays #'s

    FC= 3.5
    CC= >.5
    PH= 7.5
    TA=100
    CYA=30

    The water looks better but this brown algae showed up on the bottom today IMAG2566.jpgIMAG2565.jpg

    Ready to SLAM or ?

    Thanks in advance ...

    Started the SLAM process just in case , added 170 oz of 8.25 % bleach ( thanks pool math ) to target 12 ppm

    Readings after adding bleach

    FC= 13.5
    CC= .5

    See what tomorrow brings

    You are doing the right thing. visible algae, dead or alive, (that's dead in the pic) is maybe the best indicator of all that a SLAM is needed.

    You have a nice grasp of the chemistry involved and you caught this VERY early so I do not think your SLAM will last very long. Good work using your wits and your test kit to recognize your issue and handle it accordingly. That's TFP Pool management!!

    #'s From 5:30am
    FC=12
    CC=.5
    Water is crystal clear again , vacuumed up the dead stuff . Then I managed to spill the powder for the test kit ( was in a rush ) I might have enough to test when I get home , hopefully someone stocks it locally .

    Wouldn't bet on someone stocking the FAS-DPD test locally. I would order more powder or the XL Option which are available on this page (TFTestkits.net) or you can order the FAS-DPD refill which contains the powder and both liquid reagents to test FC and CC (TFTestkits.net). You will need the FAS-DPD test to manage your pool on an ongoing basis.

    A good test kit is an investment, not an expense.
