need your input in setting up a 90gal

[raleej337]

I’m in the middle of planning my mixed but mostly SPS 90gal tank. The tank will have a sump/fuge and the return will be run by MD9.5. For the tank water movement, I am torn between making a closed loop with another MD9.5 or use two (2) koralia # 4. For both set up I will be using my current koralia # 1 and #2 for additional movement.

 

I need your input on which set up should I pursue.

 

Thanks!
