The Hammerhead pushes 6000gph at 0' head.

So 2 x 1.5" drains will allow me to diffuse that pull sufficiently in your opinion?

As for the outlets...I can keep the pair under the overlow and have another pair of 90s in the bottom and spread them out some. Any reason the pairs should or should not line up? Is staggering better?

And of course 1" outlets will be easier to hide. I'm not sure with fittings like these whether or not flow can really be broadened much by using a larger fitting. I intend to use your omniflex nozzles. Perhaps they don't come in 1.5" I'll have to look.

Regarding the omniflex tho...in Dez' build they appear to be 45deg fittings. Would that not push flow up and work against the sump returns? 90s would push all the way to the end (all working together) and then hit the pane and go up and then pushed across the top. Maybe the 45s are better what do you think? Better for a sandbed I'm sure.

Two more outlets:
