I don’t have a sump. Should of mentioned that the tank is a 20 long AIO. Installed the UV right in front of over flow.Nice! Didn't realize they made them this small and cheap. I'll definitely try to find one like this. Can I put it in the sump or should it go in the display with the dinos.
Everyone recommends to put in display anyways. It’s not that big and not to much of an eyesore. Looks better than unhappy corals!! Hope it works as well for you.
