Flow in Mr. Aqua 12 gallon long aquarium

So I finally picked the aquarium to house my new reef. The Mr Aqua 12 gallon long aquarium. Mainly every one that I have seen using this aquarium on forums has put the filter on one side and a mp10 on the other. I will be drilling and using a sump so I am trying to build random flow into the return. I wanted to get everybody's opinion on the plan. The current thought is to put the overflow box at the back in the middle of the aquarium, then have a return outlet on either side facing to the middle with either a flow alternator inline or an innovative marine spin stream on each end. What are your opinions on either of these ideas or do you have a new thought? Thank you!

 

bump. It appears that literally everybody that has this tank has an mp10 in it, oh well I guess thats what I'll be going for.

 

or two Tunze/ Koralia pumps on either side
