DIY dual overflow

[MoreDakka]

Hey all,

Just getting into this fish tank stuff. Had our 45g running for about 6 months. 33lbs of live rock from Tonga.

The setup I have works but the HOB filter and protein skimmer are ugly and the protein skimmer is really noisy. So this prompted me to get a sump system going. Got me a Little 10g tank that I'm going to baffle off and put a refugium and a sponge filter in it with my protein skimmer

Just got The pieces for the dual overflows. The 2" abs isnt in the pics but here is the start.

till not complete but now this leads into a question about my tiny sump.

First off here is the dual overflow running (nothing glued, I like seeing it run before getting it into the system).

Missing the auto-start system (hose drilled through the top of each side then connected to an air pump or powerhead)

Here is the question about the sump:
It's only a 10g sump as that's all I can fit under the cabinet. Here is a pic:

Now the spacing I've written on the tape there ( 4" - 1" - 1" - 7.25" - 7.5"). The right most will be the skimmer, middle will be live rock, baffles then return pump. So the question, will this work? I need a small skimmer, was looking at the NAC3.5 Cone or the NAC6 (might fit 7.5x9.5 is max size if that whole area used). Leaning toward the NAC3.5 as it's price is more my area. Tank is a 45g and sump of 10g water volume of 50g ish I would think so the NAC3.5 would work but will it wooork.

Was also wondering if I should have some sort of foam filters to filter out large particulates that make it into the sump and where I would put that?

Thanks.
