Thoughts on reef savvy ghost overflow for 40b?

[ice fish]

Piecing together my next tank which will be my 40 breeder and was interested in trying out the ghost overflow from reef savvy. Any thoughts on these and what you guys think if it would be good for my 40? The tank is going to be my experiment into the SPS side of reefing.

Their new one is 18" I believe. I know they are awesome, and would work great for any tank. Would probably be a little much for a 40, but would work great. I like the small size inside of tank..
