Hello! I am new to the hobby and am in the process of planning out my first reef tank. The tank that I have selected is 48" long and 24" wide and 20" tall with two flexible return pump discharge points in the middle back of the tank. I am very interested in the Vortech MP40 powerheads but I don't think I will like the look of the powerheads mounted to the side of the tank as I intend to put the tank in an area that will be frequently viewed from the front and both sides. I am really interested in mounting the powerheads to the back of the tank (which will be up against the wall). So here is my question. Will a mixed reef tank with the dimensions listed above be okay with running two powerheads on the back of the tank (will likely go with something like the Reef Breeders Reef Power RP-M V2 as the Vortech will be too thick to fit between the wall and my tank) or am I far better off by sucking it up and dealing with a little less visually pleasing look and mounting the two Vortechs to the sides of the tank? Also, the tank I am getting is "rimless" so if I do mount the powerheads to the sides I will want to run the chord down and not up. I would also love any tips on placement for mounting them to the the back (specifically height) or sides! Thank you!
