    Cool Water looking a little cloudy after a heavy rain storm last night...

    I'm a pool newbie with Mym pool installation being completed in May of 2013. I've kept it uncovered all winter and the water has stayed crystal clear. However, a heavy storm passed thru last night and brought heavy rains to our area and this morning the pool looked slightly cloudy. In the time I've had my pool it has never been anything but crystal clear. I admit, I am quite meticulous about keeping my pool leaf and dirt free and what I consider slight cloudiness might not be considered a problem for some people but it bothers me. So my question is this. What's causing the cloudiness? My PB suggested mixing 1/3 of a bag of shock in warm water in a large bucket and pouring that into the pool as I run the pool cleaner. Does this sound like a good plan of action? Or do I just let it go and see if it clears on it's own?

    Any advice would be appreciated.

    Thank

    Hi myoung36! I'd give it a couple of days and let the filter do it's job. Sometimes your CYA will get out of whack after a rainstorm. If it hasn't cleared up after a few days you might check your water chemistry and add accordingly. It's nothing to freak out about.

    That does not sound like a good "plan". Rain rarely causes a problem. I would suspect a chemistry issue. Our recommendations are based on test results and then careful dosing to achieve a desired result.

    How are you testing your pool?
    What are the test results?
    How are you chlorinating?

    Just saw you have a SWG. How often are you testing you FC and CC? If you need to supplement the FC, we recommend using liquid chlorine / bleach.

    ^^Agreed. I intentionally divert rainwater from my roof into my pool, and it doesn't get cloudy. You most likely have a chemistry issue, likely not enough FC for your your CYA level. If you can give us a little more info about/including test results, we'll try to help.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    I have to say that it takes an enormous amount of rain water to effect the CYA level. It is actually unlikely you would
    get enough dilution from a rain to make much of a difference at all.

    Even if it does dilute CYA some, it wouldn't be the cause of cloudy water.

    Be very, very, careful about the need to add CYA after a rain, even a big long storm.

    I wouldn't be at all surprised if you got a lot of fine dirt and more importantly, fertilizers washed into the pool. Ammonia compounds make thing green - lawns, pools, you name it.

    Rather than just chuck a bucket of "shock" into the pool without knowing your CYA or CH levels (one or the other will be raised by the "shock") how about posting some test results? Then you can attack the problem scientifically, with facts instead of inuition.

    Another vote for FC levels have fallen below min for the CYA level.

    I'll bet some liquid chlorine would clear it up. 😎
