What size UV unit??

[ShawnSaucier]

I have a new build I'm working on. Approx. 190g display. I would like to run a UV unit but am not sure on what size to purchase. Any suggestions on sizes and makes?

Emperor Aquatics has a sizing guide and flow chart that sets them above the rest in my opinion. BRS carries them and has sizing guide on site. You will need to plumb in as a bypass to get full benefit as more contact time is what kills the nasties.
