You adjusted salt? Why? Did you measure the salt using a K-1766 test kit? What is the true salt level?
SWGs, especially Pentair ICs always show lower salt as the water temps drop and they stop producing chlorine below 56F. Once your water drops to 60F, it's just better to turn off the SWG and manually chlorinate.
As for cleaner - never need to if the water is balanced. I haven't needed to clean mine in years.
I'm going to suggest something now that will likely cause you consternation or to raise an eyebrow - you need to not listen to your PB anymore and, unless it's a warranty call on something, I'd just ignore what they say. PBs know how to dig a hole in the ground, add pipes, concrete and tile and call it a pool. Beyond that, they typically know next to nothing about how to properly run a pool.
If you have questions, ask then here. You will get straight answers.
