On my 210g I am running two FX5's. I have them coming up the back middle of the tank and then outputting to each side at 24". So basically the 48" in the middle of the 6ft tank is circulating. This leaves enough on the ends to do the dirty water intakes. Because I used the 3/4" PVC I was able to use suction cups on the unsupported ends and used the elbows of the PVC as the other holding point. The suctions cups I use were made for Eheim heaters. This cliped around the PVC just right and has two large suction cups to hold it in place. If it can hold a heater it will hold the PVC.
You might want to experiment with your spraybar length and holes. I used a strip of pegboard as my template for drilling. This places the 1/4" holes every one inch. This gives a nice output at the 24" length but still moves the water around. I read of another person taking the holes out larger and making the bar longer to achieve almost no current.
