I currently putting together a 60 gallon planted tank and am going to upgrade the spray bar for my eheim 2217. I have drawn up acouple quick sketches in autocad and would like your input. The tank dimensions are 48x15x17. I am changing the spray bar a bit to help with the pressure in the tank, i will have a ball valve at the bottom and a barb to connect the tube from the eheim to the diy spray bar. Figure c is 36 inches long. Figure b will be 48" long and the perpendicular spray bars will be 14" long. Figure a will be 24" long. The pvc will be painted black to help hide it in the back of the tank, dont mind the red in the pic i just didnt texture thoes holes so they can be viewed easier, all pvc pipe will be schedule 40 1/2". Which spray bar would you choose and why?
