I also kind of started to think about how the closed loop would be plumbed. Still not sure yet but I am trying my best to avoid over the back! I think I will go through the extra bottom bulkhead I have and then up to the eurobracing. I took a picture of how I think I will have the return get up to the top. It will be painted black and also have a rock column in front of it, so it will not look too noticeable I don't think.
I guess the one thing that may happen is that the flow on the left side will be much weaker because the return would be on the right side. BUT the mag 24 return from the sump will be on the left, so I think that will even it all out. What do you think?
Im also wondering if I do it this way how to have the outlets. Im thinking about 6-8 but Im not sure. Its a big 6000 GPH pump, so I think it could easily handle 8. The head loss is just under 5' and no 90's until it hits the top "t". The outlet of the pump will be directly below the bulkhead.
What would you do with the 2" outlets? Leave them just as 2" 45's or 90's? I do not want to restrict a lot of flow coming out of them. Im kind of lost right now on this...
