In which case you are in maintenance mode and need to keep FC between 5 and 10. If the N2 is working for you, you can stay closer to 5. Phosphates are food for algae. If you don't have algae, the phosphates do nothing. Very few here ever need phosphate removers, and those few have persistent and tough mustard algae.
I have never heard of a UV light in a pool. If it can damage the repro cycle of algae and insects more than sun light it may well break down your chlorine faster. I do not know.....

DELTA UV is what I have. Small description of how it works-

E and ES Series both offer an incomparable and safer pool experience for your family and friends… Silky, smooth, odorless and salt free.

The water circulates through our Delta UV sanitizer that uses the type C ultraviolet rays to completely purify water deactivating all the dangerous micro-organisms resulting in the cleanest and purest water possible for your pool. As small residual of chemicals are used in order to destroy any micro-organism that do not find their way into the UV sanitizer.

I am going to check the plumbing arrangement to make sure Chlorinator is down stream of UV system.

I will ask Ben to look into it.
