Mp40 placement on 72” tank

[Eder]

Have a waterbox 230.6 in process of finishing and have four Mp40s. Right now we have two on each side just randomly placed. Would y’all leave them on the sides or place two on the back? Have never placed any on the back but this is going to be an sps dominant tank once up. Thoughts?

My opinion, I think you would be wasting the powerhead going from the back. If you put them low on the rear side it would have a chance to expand it’s path of flow more and might be ok. On my 180 I have two small gyres running on the back wall and could really use another right in the middle.

Anyone else?
