So maybe take the Sicce pump out of the sump and run it externally inline with the UV? Would that help?
If you still plumbing, I would try to do the following: (1) run the UV vertical if possible (many of the comments I've read on UV sterilizers suggest running vertically as you get more time in the UV--wasn't possible for mine because my wife did not want the UV outside of the cabinet underneath the tank), (2) run the pump externally inline in a closed loop with the display if possible. I think that is what I am eventually going to do. Get a new DC pump and run it externally with hard PVC coming out of the display tank at the top, dropping down the back and into the external pump, through the UV, and then back up to an outlet on the other side of the overflow. Good luck. Please post if you have similar flow or heat issues.
Thanks for the advise, I did mount it vertical. Unfortunately I plumbed it out from the return right back into the return as I couldnt think of another way at the moment. Since its Identical to my return pump and have identical desired flow rates (950gph for algae uv & a out 1000 for 10x turnover on my refugium based system) and since the OUTput plumbing on the UV runs inches away from my teturn plumbing going up to the Display, I think I'm just going to plumb my UV output to run up as my return. Perhaps with a valve or two where it integrates with the existing return line so I can run one or the other if I dont want UV running for servicing or if I want to slow down the uv for protozoa and just adjust the valves so together they equal my desired tank turnover rate. I'm kind of entertaining the idea of just quick and easily running the uv output up & over the back of my display tank to make a closed loop that way. It will then be pointing down into a deadspot in my tank. I can then just keep running the original return but at a slow 200gph or so just to keep a similar flow pattern with the dual output lockline that it has pointing from the middle down & out to each side of the tank
Very cool. Running it vertical like that, are you getting any micro bubbles? I switched mine up again (see below) and now I’m getting micro bubbles.Thanks for the advise, I did mount it vertical.

So everything closed up.
Well...it has been somewhat sporadic. The UV raises the temperature about .5 degree every hour. So I haven't set a schedule yet. I'm guessing that by your post running the UV on and off multiple times is not good for the bulb?
While your short concise responses are appreciated, some more explanation would be much more helpful to not only me, but others who may read this thread in the future.
