Whew... I guess this tank is just a weird size.. the 24" length is killing me... because it's only 12" deep and 15" wide and 2 of those inches are in the back of the tank where nothing will be anyways... That's why I was looking at the Prime HD originally..because it seemed like the perfect light for the depth and width of the tank..
But realize now that I will probably lose 4-5 inches on the side of the tank... which might be okay if I plan things well enough and put lower light corals on the outskirts..
Another thing I have to keep in mind that this tank is in my bedroom and my partner and I have different sleep schedules sometimes.. so the thought of having to get 2 primes for this small tank might be overkill and my wife might kill me if it is so bright that she can't sleep lol.
