Thanks PC.
No it does not make sense, I guess I don't understand the unit operation. I had the aquapure set for 50% before I reduced it down to 5%, CL levels have come down, so I'm thinking that the cold temp we saw these past couple weeks might have helped keep the levels high, Right?
Yes. Cold temps in general (winter).
So in cell reversing it is still producing CL?
No.
The correct answer is yes, it still produces chlorine. What happens when the polarity reverses is the direction of ion migration will change to opposite. But because both of your plates are coated with catalyst, they are both able to produce chlorine. Now if you were to reverse polarity on the non-reverse polarity cell, it wouldn't produce any chlorine. That's why reverse polarity cells are more expensive, they require double the amount of coated plates, whereas in non-reverse polarity cathode is made out of bare titanium. The only situation where you would see chlorine not being produced in reverse mode (apart from controller failure) is when the plates are worn out more on one side. But then it wouldn't clean itself properly anyway, because cleaning and manufacturing chlorine are two sides of the same process. Here is a general article on electrolysis for those who are interested:

I thought the cell reversing was to clean the cell.
It is
What about the 3 lights remaining on is that normal? Flow, cell reversing and cell resting lights.
Yes, as long as you loose two lights within 3 hours.
Could the flow sensor be bad even if there are no codes showing up?
Absolutely, I've had only a "no flow" display before, and it was the sensor.
