2.5" hole I believe is good enough for over 2000 GPH. With a hole that large, I wouldn't worry about what size pump you get. 5 cycles per hour, which is more than enough for your stocking level
, would be roughly 1050 GPH. That overflow will handle that no problem.
$800 is a steel I think. I bought a 180 for $800 with a Fx5, crushed coral, heaters, lighting and more and sold it without even using it for $500.....
