Wanting to eventually do mixed reef. Would 3 of the lights work on my 125, 72x18x18? It has 3 center braces across the top so 2 36 inch lights won't work, I want to tank mount them. I was thinking of 3 of the Prime HD LED Module (Black) Aqua Illumination, on each 1/3 section of the tank, mounted with the arm kit onto the back of the tank.
