Personally I’d stay away from junk black boxes, they are crap and your coral will grow like crap. T5 is a better option for even par and coverage, you can customize the color with different bulbs. Also I would recommend a t5/hqi combo light for really good growth and color, you still can’t beat metal halide for relocating the sun. I the you can search “adv 48 hqi” on eBay and find a decent light. Good luck.
