Hello everyone, I’m sure this has been discussed 1000 times to try and save some time from going over the 1000 threads that have already been started. I’m curious if someone can answer some plumbing questions I have for my UV sterilizer. I just received the aqua ultraviolet 25 W for my 100 gallon. I’m curious what is the optimal plumbing solution? Sump to sump or sump to display? I had originally planned on going from my skimmer chamber to my return chamber in my sump which would intern flow back into the display. Please give me your thoughts and reasoning thanks.
