Ahh..... no.....
Let me add to this addition - no - .....
No UV in the Tank / Refugium / Sump or in the water circulation or pumping
system.
Yes UV before [prior] entering the pumping work / filtering / water
circulation system.

But for those that thinking of getting UV, then NO.

What UV inline of a RO or RODI is to kill any bacteria or such before
entering anything from this water source.
