Double-check my plumbing

[W1ngz]

Planning a new tank and while I'm waiting for the tank itself to be built I've kept busy 3D modelling the stand and the plumbing. I'm hoping someone would take a quick look and offer any suggestions, particularly on the return section. The return pump will be feeding the display, a small frag grow-out tank as well as a manifold. One port on the manifold will drive a reactor with carbon and GFO, the other will probably just be used for water changes.
The red pipe is the emergency drain off the overflow, dark blue is 3/4 return plumbing, medium blue are 1" drains and the one light blue is the drain from the frag tank.

Looks good.

Personally, I like to just keep the return line designated as a return line, and run everything else off from another pump. Pumps are cheap, and Doug that gives you some more options with that water as it recirculates.

Thanks for the input. Keeping it separate is definitely an option, and I already have the pumps I would need to go that route. I think I want as little 'stuff' as possible down there though.
