Herbie overflow plumbing question

[Cmartin97]

I am beginning my plumbing plan for my reef ready 48" 88ga Display Tank. I have a Ruby Elite 36 sump and I'd like to plumb in my fuge and overflow using the "Herbie" method. Could I get some feedback on the design and let me know if I'm missing something?
