3. Should the refugium water level be the full height almost and only having room for (power outage) overflow on the right side? Eventually, I may try to add auto top off then also which will be level switched from the right side.
Thanks for any ideas.

1) It depends on what you want to grow in your refugium. Some Macro algeas like Cheato like higher flow and will do better when allowed to "tumble" freely. Other macros may not appreciate that much flow. Also, you'll most likely not be able to keep sand in your fuge and the draining water with blast it all out and into your pumps :eek
2) The longer the water takes to get from the entrance to the exit, the better.
3) Always leave enough room in your sump to hold all of the overflow water, water in your return lines and then some.
