XP3 is a great size choice for that sized tank. On my 120 gallon I actually used the include jet output that comes standard with an eheim intake. I sort of set it up "ADA style" with both intake and outlet on the side of the tank. The inlet is about 2 inches from the substrate toward the back corner and the outlet sits closer to the front and is about 3 to 4 inches below the surface of the water with the nozzle aimed upward to create some surface movement without splashing. What I have observed is that water hits the other end of the tank goes down and then loops back along the bottom. I am very pleased with the results of this. Never thought I wouldn't use a spray bar, but this is working out good so far.
You may want to try this first and then add the bar later if you really think you need it. If you want a spraybar try something like this Install set
and this Install set inlet
