    Definitely keep cover off during the day as the sun will help burn off CC's.

    Night time cover on/off is your choice.

    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.

    In addition to helping burn off the CCs, leaving the cover off can extend the life of the cover (assuming it's a solar cover in contact with the water.) The high FC will reduce the life of the plastic making it brittle.
