If I was to get an Aqua UV 40w, what pump would you recommend for it? So basically what I'm getting out of this is that I should get a second return pump and get the water right after my mechanical filtration and put that water through the UV, then the water finally ends up in my return pump chamber.Dude you are getting a lot of bad advice from people that have probably had a tank for 3 months and don't even have UV. It boils down to this... if you want 25w to work, you must pull water out of your display, run it through the UV and then return it to the display. This us called a closed loop display. People are recommended certain pumps. Those pumps advertise a certain flow rate but you will be lucky to get 25% of that advertised flow rate. For something as important as killing protozoa you want to get a timer and a gallon jug. I don't even recommend running it inline from your sump's return to display. It's just too small. You won't have a high enough turnover rate once you set the proper flow rate. If it's not too late, send it back and get a minimum of 40w. Another thing to consider is that if you have a proper quarantine protocol, you shouldn't need to target protozoa.
