How's this sump design

[sasq40]

This is my planned sump for my 66 gallon. I built the stand so my 50 fits prefect under in, so that's why I'm planning on taking 10g from the one side to use for auto top off. The rest will be used as showed. Thinking of doing a mainly clear vinyl hose plumbing with ball valves of course.
Let me know what your think and what you'd change

Make sure to have filter socks on your drains. Otherwise any type of reactor you plan on adding will just turn into a canister filter. Maybe run the refugium section off a t from your return pump instead? Otherwise it works. I'm a fan of the style that uses a trap for bubbles to rise, then filter socks, then. 'fuge/skimmer sectíon, then return section. This configuration works well, and allows more water volume for the refugium.
Oh, and look into DC pumps also. They are adjustable and use less power for more gph.

I've read some people like the drain going to refugium because of giving unfiltered for pods. Instead of a sock in thinking of building this http://www.nano-reef.com/topic/325631-tired-of-cleaning-nasty-filter-socks-in-your-sump/
