Pump for 30gallon cube

[cpllongjk]

I have an oceanic 30g cube tank. I have mostly sps in my tank.
I currently use 2 tunze nano 6025s and they work well but im looking for something better.

What model ecotech should I get, and where should i place it? Also, what mode is best for my tank?

The dimensions are 20"x20"x20" approx

I believe this would be a perfect size tank for an MP20. You should be able to get a gentle 1/2" wave.
