We recently got the UNS R90 from ADG. It's obviously smaller than the 150 they have in display but the layout, build, and the electrical cabinet idea are in essence the same. I came across your question here by trying to find out other users or threads with the same, or at least similar, tank and as you very well point out: there aren't any.
The reef line seems to be relatively new to UNS and I think that's the reason why there aren't many reviews or information from other users. I think I'll start documenting my tank build as a way to share the experience and maybe contact other possible users.
For now I'll share some ideas based on our experience, positive and negatives:
- Very neat looking, no equipment hanging from the tank and when the cover panels are on it's all neatly covered and contained
- Love the panels: detaching them and attaching them is super easy with the magnets and you have full access to the sump when needed, without bars in the middle or doors restricting your move
- Although we like the electrical cabinet space idea, the actual execution of placing controllers and all equipment in there did not work for us. This is mainly because of the size and amount of equipment we have (Neptune Systems) so we ended up placing controllers and power bars in a separate cabinet and left only dosing systems in the UNS cabinet. The R150 has a bigger cabinet size but I think it still would have been a little challenging for us to cram everything in there.
- The ATO container is well built but pretty heavy, big, and it sits on top of the refugium/biomedia chamber cover. Accesing the refugium or biomedia chamber requires moving the ATO container aside and at this point we are limited to submersible refugium lights if we want to set up a refugium. Right now we're using media in that chamber. I believe the setup is pretty much the same in the 150.
There's more to say but I think it'll be easier to upload more detailed pictures to my tank thread and answer specific questions. Overall we like it, I'm a little worried about how "new" the line is and how little information is available yet but hopefully as time goes by there will be more feedback. Let me know if you have specific questions I can try to answer.
