to your original question, based on my experience I dont think that the color output of this light is going to be very good.

19 blue, 19 royal blue, 9 10k and the last 8 are 6500k. Based on my experience this mix will give you basically no red spectrum, but plenty of blue/green/purple. not to mention the claimed 225 par at 24" below the unit says nothing about in the water... could be deceiving. I wouldn't recommend it.
