Hey guys. I'm new, so take my advice with a grain of silica. I have been working on models for my tank setup so am browsing through DIY forums, but I might have some good comments.
Dual overflow-I think that's to split up the flow from tank in case you want one line to the sump, and another to a fuge. If you're just using one for both, you could just use a Y-adapter directly under to cut down on piping/tubing. just make sure the combined diameter matches that of the final downspout.
You don't need to drill any holes (sump). Overflow from tank can drop from above, and return line from fuge can go right back up from water.
baffles are just to slow things down. slower water has less ability to hold bubbles. They can be as tall as you want (as long as there's enough room so the volume of water flowing over will stay within the confines of the container)
The limiting factor of the whole system is the overflow. the fuge will not spill over as long as the tank itself is not overfilled. even a 40GPH return pump would work(not well mind you), and the level in the tank would drain to the overflow initially and then match the return after that(40GPH). IMO I would not get too close to the overflow rate with the return pump rating. give yourself some room so your tank doesn't overflow.
Imagine a system with a 1000GPH overflow and a 980GPH return pump. One of your anenomes uproots and settles aginsed your overflow inlet. That might cause your return to outperform your overflow. Your fuge empties into your tank, which in turn, empties onto your floor
Sorry to be so windy, just hoping to contribute.
