I currently have a 75 gallon frag tank. It is 48" long, 24" wide, and 16" tall. I am running 2 kessil A360WE's over right now. Possibly considering switching to the X version to get the angle adapters and get better angles on them. I am also wondering if it would be a decent idea to run 4 to eliminate shadows and get a better spread since the dimensions already max out the spread of the lights anyway. Any thoughts?
