Let me know what you think about this setup please! Any advice will be noted!

refugium will be about 10gal operating
return tank will be about 8.5gal operating
filtration tank will be about 7.5gal operating

I was aiming for 100gal of water when operating. I realize I will need to top off the return tank quite often.

Looks good to me. Just don't put Bio-Balls in your sump if you plan on keeping a reef tank. Use live rock or a filter sock. Also make sure you have room for the 8.5 gallons of water in your display tank, should your overflow stops working.
