Im not sure what a 25cube looks like and such.
But if you plan to upgrade at somepoint. The Wireless is something to consider.
I actually sync them and even antisync them. The random flow patterns keep the corals growing in diff ways.
I take advantage of ecotechs power head placement suggestions and start from what they suggest.
Now, my four mp40 are controlled and synced to my apex wxm. I will say being able to controll the pumps wirelessly works great.
But if you plan on only having one powerhead then stick to (EDIT) NOT WIRELESS
