My 72 gal Bowfront build

Hey everyone, I'm new to the sump world but a friend who was moving hooked me up with his drilled 72 bowfront with stand. I plan to custom make my sump but I need ideas for my hardware and design.

I also have a 72 bow.im using a 20 lg as a sump/fuge with mag 9.5 for return. if I could do it again I would prob go mag 7 (unless you run stuff off your return).the only thing I hate is there is not to much room on either side of the sump for stuff,but if your going custom you may be able to over come this..OH one more thing,keep in mind what kind/how big your skimmer will be.think a head for reactor placement( i.e.,carbon,gfo).congrats on the new tank..any questions ill try my best to help..

 

I was think about putting a 30g or a 40 breeder in as the sump.
What else do I need under the tank: ATO, reactors?
How about in the tank for circulation or design for the sump?
What about substrate size?
