    green pool

    Hi everyone...I'm new to the forum and was hoping someone might be able to help me out. My pool had been blue but very cloudy since last year. This year, I started off with the same cloudy water as soon as I opened my pool. I went to Namco and had my water tested and they said my alkaline was high so I was advised to use 2lbs PH decreaser for a 21'x41' above ground pool. The sales guy then said to put in 2lbs of shock. The next day I looked out and my pool is green and has been for 3 days. Hope someone can help.

    Thanks in advance!

    Welcome to tfp, adamtheaxe

    Cloudy water is almost always a sign that you have algae growing and you need to do the shocking process.

    To do this most effectively you will need your own appropriate test kit. See this link for these kits: I like the TF-100 most bang for buck.

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.

    Re: green pool

    What are your current test numbers? Is the water cloudy green or clear green? What is your water source? Clear green most likely means metal in the water. Cloudy green means algae. Go over to Pool School and read up on how to shock your pool. What test kit do you have? Either of these is recommended, and required for the shocking.

    Re: green pool

    Thanks for your replies. All I've used as recommended by Namco are the test strips where you just dip them and read the results. Those numbers if it's of any help are:

    FCI: 1
    TCI: 1
    Alk: 120
    pH: 7.2
    TH: 0
    CyA: 40

    Re: green pool

    unfortunately, test strips are the worst ... so that is not much help

    Order one of the test kits in the link provided and while waiting, read through Pool School a few times to start to learn the truth about your pool chemistry.

    Then post up the test results when you get the kit and we can help get you straightened out.

    Ask questions as they come up.
