    Milky Water

    Can't seem to clear my pool water. Had some iron staining and used Stain Free made by Natural Chemistry. Worked great. Waited a week and shocked the pool. Been cloudy ever since. I had the water tested and found phosphate. Used a product to remove that. Still cloudy. Was using a Waterway cartridge filter. Been running it 24x7 for 3 weeks. Still cloudy. Pool dealer gave me a DE filter to try. Been running that for 2 days. Still cloudy. Have tried clarifier. With no luck. The chemistry is perfect. My pool is 35000 gallons. Any help would be great.

    Re: Milky Water

    Welcome to the forum.

    Cloudy water tells us your chemistry is not perfect. Pool water chemistry is what we teach but you'll have to help us by providing a complete set of test results like this

    pH =
    FC =
    CC =
    TA =
    CH =
    CYA =

    Pool store testing won't work.....it's bogus.. You must be willing to invest in one of the two test kits we suggest and then willing to learn what we teach. It ends up quite simple but the beginning is reporting your own test results.

    Re: Milky Water

    Ph=7.2
    FC= 3ppm
    TA= 80
    CYA=50
    not sure what CC and CH are?

    I have an HTH 6 way test kit. What should I be using?

    Re: Milky Water

    The two most accurate ones are found in Pool School - test kits compared.

    CC's are combined chloramines and I don't think your test kit tests for them.

    CH is Calcium Hardness and not really very relevant to vinyl pools unless it is quite high.

    How are you chlorinating your pool?

    I am using a chlorinator. Holds 11 3" tabs.

    I also shock with a product called Austins Pool Tech. It is 12% chlorine bleach.

    Not sure if it matters, but the chlorinator is a Pentair model 320 inline type.

    Re: Milky Water

    HI there

    It sounds like you've got something in there eating your chlorine and just waiting to turn your water green. With CYA of 50 and FC of 3, your chlorine is too low. To clear up algae, we follow a process we call SLAM

    Shock
    Level
    And
    Maintain

    The amount of chlorine you need is dependent upon your CYA number and you are constantly adding CYA by using those pucks

    Here are some links to get you started

    Re: Milky Water

    Hi
    Have shocked the pool a few times to 10+ ppm and no luck. Still cloudy water. Having a grad party this weekend. Desperate for answers.

    - - - Updated - - -

    Also,been using pucks for 13 years. Never an issue. Living in the north I get a good amount of water turn over from rain and snow. Every season I probably change out at least 1/3 of my total water volume.

    Re: Milky Water

    The SLAM article above should help you out. It's a process, not a one time addition of "shock."

    Shock level for 50 cya would be 20FC. And with CYA at 50 your FC shouldn't drop below 4 or you have an invitation for an algae party.

    The more chlorine I add the cloudier it gets.
