Need some ideas for UV, pictures inside and I've so far failed....

Hey all,

I'm trying to get some UV setup in my tank, as I've been battling Dinos for a while and need them gone for good. I had a GKM in there but it wasn't enough to keep them at bay (it also died pretty quickly on me)

I had a pretty good plan, screenshot below:


That's a COR15 (I have Apex all the things) and a Aqua UV 25w. The plan was to close-loop it and keep all the water over the tank (in case of leaks, power failures, etc). All was going well until I tried to power on the COR15 to do a leak check and it wouldn't start up without being submerged. It always says "DRY" and spins a bit. I figured I could prime it by inverting the input tube and filling it with water...but alas, no dice.

I thought about just keeping this under in the sump but there's a whole lot of reasons I'm not a fan:

1. I'd have to suck water from my future and return it to the final return pump area, bypassing my skimmer and GFO/Carbon.
2. There's not a ton of room here.
3. Water would be flowing outside the tank, and puts in a risk for leaks

I also thought if I added a second return pump in the return chamber, I'd be able to work that...but I'm 99% sure it won't fit, and also leaves me with problem 3 above,


So I'm looking for some creative ideas. There's a last resort where I could get a pump that doesn't need to be submerged to start and I'd probably be ok. But again, that's a last resort as those suckers aren't cheap and I've to redo some plumbing.

Thanks in advance

If you check the index page out in my build thread, I've detailed how I setup my UV to run in the space over the sump.

That's a pretty interesting read! How did you end up bleeding all the air out so you didn't trap a bubble?

I held my thumb over the exit tubing and then alternated the flow (min/max) until all the air was blasted out. With the lights off you can see any bubbles passing through the tubing as "pulses"; once those disappear and you get a steady light there's little if any air left.

Ideally, mount it facing the other way so it's less work, lol.
