GPH questions for Herbie

[DragonShout]

I'm wondering how many gph can be expected to flow through 3/4" vs 1" etc overflow lines. Fairly straight runs I'm sure, the bottom of the sump will be around 30" below the bottom of the tank.

I'm not sure if I'm going to do two corner overflows, a single center, or even HOB that I'm using now........ I ordered glass and I'm wondering what size bulkheads and all that other fun stuff.

I found this:

"What size are the bulkheads, and what is the flow capacity of Deep Blue Reef-ready tanks?

Deep Blue Reef-ready overflow systems employ 1”drain and ¾” return bulkheads, and are capable of up to 600gph. Most size tanks have a single overflow column in the left-rear corner; some edge tanks have a center-rear column, and our largest tanks have dual overflows in the rear corners for flow rates up to 1200gph."
