    What FC level is ok to put solar cover on.

    We just when through shocking our pool for several days because of high CC levels. We past the over night test Thursday night and I checked it again last night just to be sure and we still passed.

    We ordered a new solar cover this year and it is still wrapped up. I didn't want to put it on the pool when there was still a possibility of algae. Is it safe to put on now or should I wait until the FC drifts lower? Here are our numbers:

    FC 9
    CC 0
    CYA 45
    pH 7.5
    TA 80
    19,000 gallons
    Stay-Rite System 3 Cartridge filter
    IG vinyl, MasterTemp 400 Propane heater
    Intellichlor 40 SWG, 2006 Taylor Test Kit with Speed Stirrer
    1.5 HP Pump

    I don't think it really matters, you're not over recommended FC by much.

    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.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    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.

    Oh, this reminds me. Does anyone add LC while the cover is on? (of course pulling it back to give yourself some room)
