Heres my plan. Will it work?

Now for questions!
1. What could provide the mechanical filtering I want for section #1?
2. Would the slope of acrylic on the right side of section 2 be ok? Or would I need to leave it flat. (FIY: the pump would be under it otherwise.
3. Whats a good pump?
4. What dimensions would I need in order to filter 2 10 gallon tanks?
THX
