My idea, opinions please

If your considering Led's you may want to consider Kessels, they would work well in those spaces hanging.

What I'm saying is the pump might have to be overkill to be able to handle the head height. Instead of just throttling it back for the two nanos, as that would put extra load on the pump. Run a third line, a recirc line if you will back into the sump with a ball valve too. Will just help keep the pump working longer.

Also with pex, not traditionally used for aquariums. Will get the same out of flexible PVC. And I gotta ask how the pex will be hooked up to the pump. Will the crimp be submerged. Do crimps rust? What are they made of ?

Is use flex PVC. If you're having trouble finding any pArts let me know I retail them out sometimes through my aquarium maintenance company.

I will definitely look into those Kessil lights. They look very nice.

If I were to use Pex piping, it would only be for the vertical run up to the tank. The copper crimp rings would be several feet from the water. I would build a header from pvc which would connect to the pump and have risers coming up out of the water. Im pretty sure there are adapter available to go from pex to pvc but I really do not know ( I just did a quick search and seems I would need to use threaded fittings to transition from pex to pvc).I dont really want to use threaded fittings if I can avoid it. I will likely use flex pvc but I am open to other ideas also.

I totally see your idea for a aux line into a refugium, thanks Nate.

Don't use pex as the fittings are copper or brass and will kill your inverts

So after alot of thinking and discussions, I think I will be canceling this project for now.
We have decided that this will require far to much modification to our home and just won't give me the aquarium look I am going for.
I really want to do a rimless open top tank with at least three sides viewable.

I may end up doing one of those Innovative Marine tanks in a different location sometime this year.
Thanks for the help.

Good call. Servicing and just cleaning the glass of algae on those tall, narrow, confined tanks would have been a complete PITA in my opinion.
