I was a bit negligent in checking my FC level. Today the water was cloudy for the first time. Added the appropriate amount of liquid chlorine to bring the FC level from 0 to 4. Question: Roughly, how long will it generally take for the water to return to clarity in a 2,500 gallon spa with the jets running at a higher speed? Thank you.

If you let the FC drop too low, then you likely allowed algae to start growing and you may need to follow the ShockLevelAndMAINTAIN Process.
The cloudiness if due to the lack of chlorine, not the lack of filtration. Running the filter may never clear it up if algae is reproducing.

Thanks, Jason. I will check the water tomorrow & will follow your suggestion if the water remains cloudy. Thank you.
Quick question: Will there be any adverse effect to the auto cover if I leave it in place during the SLAMming process? Thank you.
Don't do that. The SLAM really needs the pool to be open to burn off CC's and the high chlorine certainly will not help your cover.
After about 10 hours of of monitoring the FC on an hourly basis & adding liquid chlorine to maintain the SLAM level, the water is again clear. Early this morning I checked the CC (0.5) & the FC which was unchanged from last night. (BTW, my spa is 2,500 gallons). So the SLAM seemed to have done its job.
One follow-up question: At what FC level would it be safe to cover the spa? The current FC level is 14.5. Thank you so much.

I always cover my tub within 5 or 10 minutes of adding more bleach and it is always above 10ppm. I haven't noticed any issues, tub has been installed 3+ years.
I didn't know if a FC level of 14ppm might have an adverse effect on the auto cover (the bloody thing is expensive!). My target FC is 4 - 6ppm. I wanted to cover the spa a.s.a.p. to minimize evaporation & subsequently have to readjust the water chemistry. However, in the meantime with the cover off, the direct sunlight will help to reduce the FC level more quickly. I also turned off the SWG until my target FC level is reached.
