    If your FC is 11 and you are using one of the recommended kits, you can test pH closely to accurate now.

    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.

    PH won't be very far off when FC is 11. However, for best results it is good to let FC come down a little before testing PH. FC will come down on it's own. How quickly that happens depends on your CYA level, but for a drop of 11 down to 10 it shouldn't be more than a few hours during the day regardless.

    Be sure you turn off or lower the output of your SWG.
