Sump design ?

[Maz]

I bought a 180 and I'm thinking of a sump with 2 return pumps. Basically one pump on each end of the sump underneath each overflow box. Has anyone ever seen this before? Is it even practical? I was just thinking about more flow coming from the 2 pumps since I wouldn't have to add elbows and lengths of pipe running across the sump. I guess both drains would go to a center chamber with a skimmer in it. Any thoughts?

I'm actually looking at something like this for my 210g build. It would just need to have the final return section run the entire length of the sump.

You can run it that way, although the majority would only run one. Strictly speaking, most don't count that return as flow, because you don't want any restrictions what so ever, so adding on directionals is a no no.
If your running a drilled tank, your not going to have any problems with it, as long as the flow is under the total overflow.
I guess, its always the safety idea, if one pump goes bad, you still have another running.
