Having pumps on viewing panel doesn't bother me. I actually have an idea to mount them from pvc off the eurobrace so they come down and actually don't touch the glass so my magnetic can just easily clean behind it n maybe like my tank now I have 2 6095s on each side facing each other. Maybe have to do the same with a 6 ft peninsulaAt about 2 min in on this video you can see the flow pattern of all 4 options on the Stream 3.
My old tank was a 72 by 24 by 28 peninsula, I had the same hope, the reality was the last foot had so little flow that algae and detritus became an issue, even if it was habitable by LPS and soft corals. I had to add 2 6055s hidden in stream rocks to supplement. When I upgraded, I decided no more peninsula style tanks, I now have a more conventional, back to the wall 84 by 30 by 24 and use 4 Stream 3. I think the only real way to have success on a longer peninsula tank is hide a couple pumps or do a closed loop hidden in some rock work, or possibly have a canopy that comes down far enough to hide some pumps above. It is very difficult to pull off.
