    Light Green Pool

    Alright guys I am finally posting instead of lurking. So here goes, my pool started doing the same thing as the Olympic's turning a light green. If I am reading the test right, I just dropped 1 gal of chlorinating liquid in the pool..

    FC - 14.5
    CC - 1..Not sure I did this right
    pH - 7.8
    TA - 260
    CH - 70
    CYA - over a 100

    Welcome to TFP!

    Do the diluted cya test to see how far over 100 it really is. Then do a partial drain to lower CYA to 50 and SLAM it.

    Use half pool water and half tap water, then multiply the result by 2.

    Re: Light Green Pool

    Welcome to TFP! Are you in Jackson, NJ? If so, is your fill water coming from the township or well? You have to be careful with the well water because it contains iron and possibly metals. My well water, when tested shows high concentrations of iron and/or metals so I stay away, but some people have no choice. For the pool, I use city water only.

    The good news is that after you verify your CYA, because it could be well over 100, diluting and filling the pool will not take long. Is the water green, or do you have algae on the walls. Your CC (combined chlorine) of 1 requires you to perform a SLAM until you pass all 3 tests. How is your chlorine consumption and how are you dosing the pool?

    Please keep us posted!

    Depends on your well and how far down you are. I'm from Jackson, but my well is down over 300'. My water tests out better than Poland Spring according to the DEP test I got when I closed. Jackson does have a number of older homes on significantly more shallow wells to the tune of 50-125'. It also depends on if your well driller hit a vein. I got lucky with mine.

    Catanzaro I am from Jackson, GA and I am on city water. Ok I couldn't take just draining some and then have to do it again, so I drained all the way down to 2 inches and started over.
