Or would I be wasting my money? I have 2-250 MH on a 120 gallon. I want to add a this LED to enhance my corals. It is a 40" strip 18-3watt system (54w total) all will be blue. I think they are 445mn which is the royal blue. I want my corals even on the sand bed to pop. Or would my MH just wash out the LED?
