Ended up replacing the return with an Iwaki 70 series (still get ~1000gph).

Yeah I may valve this thing back a bit. But this is a 6 foot tank and I want good flow across it. Its also going to be barebottom and really for that to work effectively needs lots of flow so no detritus settlings. But it will be set up with an option to valve it back if needed.
