If I were you I would first try placing the output on the back wall on the far left side just for the sake of looks, you could place it on the left side wall if you want to. I think your model of Fluval has the "horn type" sprayer, so does ours. We have the powerhead at the very top left front corner, aimed towards the top of the water as much as possible without creating a little tornado swirl "not sure what you call that" the top of the powerhead is approx 2" from the surface of the water and is aimed up and straight across to create as much water surface agitation as possible. If there is any way for your to shorten the output on the Fluval water output so that it pushes water out at the very top of the tank at the top surface of the water, all the better. We were not able to do that on the FX5 so it sprays water out about 3" down from the water surface. But we are making up for that with the Cascade spray bar. I think what you have will be more than sufficient for your 55. One of the most aggravating things to me is trying to figure out where to place the air stone so that it does not create little bubbles, because there is so much water movement going on in the tank. You can tweak this some once you get your fish in there and see how the food moves around and where their poop collects. The canister is not going to get all of the poop and stuff. There is always a small collection of poop in a couple of places in our tank that is just too heavy to get sucked into the intake. We have some big boys that are hefty dumpers in there.
If there is any way for your to shorten the output on the Fluval water output so that it pushes water out at the very top of the tank at the top surface of the water, all the better. I am not saying to do this if the manufacturer's provided parts have to be altered. There may be some reason why Fluval does it like this. I was thinking since the FX5 is so big and powerful that the pressure may not allow it to be mounted any higher. But, if you have the option to do this and the parts provided by Fluval can be shortened or lengthened according to your preference "like you can with the intake" then it might be advantageous for surface water agitation.

Reason: needed to clarify something about the Fluval output
