    My pool water turned green. Help

    We are fairly new pools owners, just bought our home in Az last summer.
    We cleaned the pool, it's 36k gallons, added in Algaecide and liquid chlorine, and everything was perfect for three days and I go out today and the water is greenish blue. No idea what to do

    Welcome to TFP!!! Join the party and swim along with us

    So do you have test results for your pool? Are you testing the pool?

    We strongly prefer you do the testing yourself with one of the recommended test kits, The TF-100 or the K-2006.

    Both Aglaecide and liquid chlorine are consumables. And Aglaecide is not an approved sanitizer for your pool. You need to maintain a consistent level of chlorine. I suggest your start with reading Pool School - Pool School

    First thing... do NOT go to the pool store with a water sample. The most likely result is that you'll spend $300 on chemicals and be no closer to clear.

    A few questions:
    • is the pool murky and/or olive-green, or is it clear but a beautiful emerald green?
    • Do you have any kind of test kit?
    • Can you find the algaecide bottle and tell us what it say the active ingredients are?
    • How have you been chlorinating it?
    16K freeform gunite with spa; Pentair 4000 DE filter; Century Whisperflow 1 HP; Pentair Minimax heater.
    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!
