Running my return line from a Waveline DC 10000ii pump and splitting it off into 5 separate lines for 4 returns and a stub (all with valves). Also installing a check valve to prevent water from siphoning back into my sump when I cut the main pump for water changes and feeding. That's currently a problem I have on the 65 gallon reef system in my living room.
Had I run the manifold in a straight run, it would have been 3 feet long...way too much to deal with in that stand considering the sump is resting on the floor between 2 cross braces. So I made it C shaped with the connection and the check valve on the bottom and the 1" manifold above that. I also incorporated a union to minimize cost when that check valve finally stops working. A friend of mine is using 1/2" check valves on his return lines and they kicked it after about 8 months of use.

With the stand being acrylic, I had an interesting thought. So I cut a bunch of acrylic brackets, popped holes in them and plan to use my tube of Weldon 16 to just mount them to the stand instead of using conventional hardware...fewer holes in the plastic that way. I'll then use zip ties to keep the pipe attached. Theoretically that'll work like a champ. In the above photo you can see burn marks on the board where I used it to help bend my brackets after I heated them with my brand new heat gun. I hope to be able to put that thing to some use after this project.
With the existing 2" holes in the stand, I'll be able to run 2 return lines out of each hole with room to spare. I may mount some additional acrylic brackets to the top of the stand to anchor the return lines and then pop some locline on each one. Ordered the locline from Premium Aquatics per my LFS's instructions (he could only save me about $0.60 on my order). End of the day I'll have about $140 in the plumbing, not counting the pump.
