Fellas the question is to connect my new 25w UV to my manifold and return pump (m2) or use and purchase its own pump and what pump you suggest

Not to hijack your thread. But I’ve also been curious the correct way to plumb the return of the UV.

I’ve read a loop in the sump IE pull from sump and return to sump is not the best and ideally return of the UV should go directly into the DT. Is that true or only the case when you are running off a manifold?

I've always recirculated mine in the sump but I'm also shooting for water clarity and I feel like it works pretty well.

I've seen a few people on R2R size their UV to the flow rate of their return so 100% of the water has to pass through the UV. That's probably most efficient but I'd need a ridiculously large unit.

I just plumbed my UV in Dec after reading multiple posts on R2R

If your objective is parasite control then the consensus seemed to be not to recirculate the water in your sump. I have mine running off my return with the ability to route 100% of the return through the UV or just a % of it by playing with the gate value input into the UV and the blue ball valve in the middle. The black ball valve I have on the very right is mainly just left wide open unless I need to perform any maintenance on the UV.

Currently have it setup to read 350gph through my flow meter w/ 100% of the water going through my UV. I sized my UV accordingly so that parasite control was around this range..

For me my main issue wasn't whether to use one or two pumps but rather how to pump output of UV back to the display tank since i didnt want to recirculate back into the sump.

You can pump inlet from first chamber and drain into return

I don’t know what’s the correct way lol: I have mine running off the manifold with a gate valve, and returning to the sump. For me it seems to work, but I’m not sure it’s the most efficient configuration. Honestly I did it this way because it was the easiest way for me lol.

Happy Reefing my friends!
