I have an mp10 and 2 koralias on my 55 gl.  I have not been successful with sps in this tank likely due to lighting more tank flow, but lps and softies do extremely well.  The tank was started with 1 mp10 but this was not enough flow even when cranked up to full was getting no surface movement.   
 
I can't say anything about the tunzes as I've never used them.
