    Chemistry close???? Cloudy water

    My water is "clear" in the sense that i can see the bottom and see people in the water. The water still looks cloudy tho. esp if I am in the water with goggles.
    Numbers are....


    Any thoughts????

    Chlorine is too low for that CYA level. FC should never dip below 4, and I prefer to have an extra ppm for insurance. Try a big dose of chlorine tonight - take it up to 10ish and give it some time and some brushing
    to mix well.

    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.

    ^^^ yep, as Richard said, FC is too low. For CYA of 50, FC is 4 to 8 and never below 4. You can run another OCLT to make sure nothing organic is trying to take hold.

    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.
