help with rr tank design

[alittlefishy]

i am currently looking at purchising a new 75 gal rr tank. I have 2 options as where to put the overflows, 1 in the corner or 1 in the center of the tank. it seems that one in the center would give more uniform surface skimming. what are your opinions on this and i would also like some detailed plans on building a sump from a 20 long. any sugestionswould be great. thanks in advance.

Here are a few links regarding Sumps, and the third link has to do with Overflows. When it comes to plumbing and/or equipment....my toddler could probably design better, but hopefully these will help you get a start:

If I would do a RR tank that size, I think personally in the center back would be nice, also I would have the fingers top & bottom, so water can be sucked in at the bottom also, from what I've seen it also helps create an even flow by moving the water out back & low where water movement can be difficult sometimes.
Just some thoughts, read well first whatever you decide, & post the results here please!
:eek2:
