    I would raise your FC level up towards your shock level and do a OCLT, to eliminate (or not) algae as the culprit.

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.

    I've had the same thing going on. My CC was zero the entire time but the water got cloudier and cloudier over the past few days. I shocked overnight and woke up to a sparkling pool this morning. I assume it was some type of pollen. Whatever it was, shocking eliminated it.

    Red highlights are mine.

    I suggest you go ahead and complete the shock process. You have met two of the three criteria to be done shocking, but the pool is not crystal clear.

    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.
