375 and what size UV

[marinelife]

I am looking at adding a UV unit to my 375 with total water volume of 400gallons. What size do I get, I am looking at the AquUV units. My return is 1200gph and I would like to Control
Parasites and Bacteria. I talked to Several and I get everywhere from 25w to 80w. I am looking at the 80w unit, would that be over kill. I hope to run it off my return pump with all water going thru it.

I ran a 45w for a 1500 gallon koi pond. If that helps you.
