Help buying new powerhead

[Blake11rebel]

I've got a koralia 750 in a 29 tall mixed reef with sump. Im looking to buy a new powerhead to replace the koralia. If I had the $ I would go with an MP10 but thats too expensive for my budget. I've heard alot of good things about Tunze on this forum and thats what Im leaning towards. The nanostream 6025 and the 6045 are both suppose to be rated for my tank dimensions and my gut tells me to go with more flow, I just dont want it to be too much flow. Do you guys have any experience with either? Or any suggestions? Maybe theres a better option. Thanks in advance for any feedback

I have 2x koralia 750 in my 29 with sump. They are placed up high in opposite corners pointed at each other. Lots of flow up top and gets pretty light at the bottom. I am very happy with the flow, but I just have softies with a few LPS.

Thanks. The flow is ok for me, but I think I can make it better. My 750 is on the opposite side of my sump return and I get a swirling motion in the middle.
