220 return routing on reef?

Im upgrading my current pump from a little giant to a reeflo hybrid pump. Question is how do you all reccomend I run the return back to the tank. Right now there is one return right in the middle with it split. I want to have 4 returns on the tank. I need to get more flow going and really dont want to buy or put more mp's in the tank. I would love to just get rid of them.

I know a closed loop would of been the best thing to do, but the tank has been up for almost 2 years. With the reeflo im going to build a manifold underneath to run the gfo and bp and a return to the fuge. I know the pump can handle it so pretty excited about it. I cant wait to see the difference from what I have now.

I was thinking of 1.5 pvc along the back with 2 or 4 outlets to bulkheads into the tank. Now I dont know if there is a better way of doing this or not. If I run up one side of the tank and accross im most likly going to have to thave a valve on each one to balcance it correct? I can see all sides of my tank so the less pipe going up the side the better.

Any suggestions would be great before I tear this thing apart and start on it.

 

Anybody?
