    Algae and Cloudy Water

    So I neglected my pool for a bit and had a ton of algae on the walls, I brushed the walls last night and now have cloudy water this morning. I have a party at my house tomorrow. Is there anything I can do to get rid of the cloudy water by tomorrow? I don't necessarily want to shock because I don't want the chlorine levels to high for people to swim. Thoughts?

    TC: 11
    PH: 7.5
    CYA: 50
    ALK: 100
    CH 190
    I have a 35,000 gallon, sand filter, sunken above ground (so inground), vinyl liner, with an Aqua rite turbo cell SWG

    It is safe to swim up to normal shock levels for the CYA, assuming the pool is not too cloudy that you can't see someone in distress.

    You should start the SLAM process now. You might overcome the cloudiness by tomorrow, or might not.

    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.

    Start the SLAM process....now, keeping FC levels at SLAM level as often as possible. As long as you follow the guidelines for proper chlorine levels during the SLAM process, it's safe to swim as far as the chlorine level is concerned. (Please reference the articles in Pool School).

    That will kill the algae and prevent new algae growth, but won't clear the soon-to-be dead algae already clouding your pool. Once you've SLAM'd for a few hours, you should start to find dead algae accumulating on the floor of the pool. If you absolutely need to have the clearest water possible by tomorrow, my suggestion (along with the SLAM) is to start vacuuming the dead algae to waste, replacing water as needed. Run the filter 24/7. If you have a sand filter, adding the right amount of DE will help (please don't add it while vacuuming to waste!).

    If it was my pool, I'd check the CC levels before allowing anyone in the pool. If CC's are in check, FC is at or below SLAM level, and the water looks ok (doesn't have to be CRYSTAL clear but you want to be able to see the bottom of the pool for safety reasons), then you are good to go. But by all means, continue SLAM process until the water is crystal clear and you pass the overnight test.
