Hello, I'm setting up a 90Gal FOWLR tank with sump in basement. I am going to have two drain lines coming from the display tank to the sump. My question is this: Can I plumb a UV lite on one of the drain lines coming from the display tank going to the sump? If not WHY NOT. I understand the UV must have a given flow rate through it. If this is doable would it be better dumping into the refuge section or the skimmer section? The reason I'd like to do this is to keep head loss down for the return line so as to achieve a better flow rate. Thanks for your help
