If you're looking for blue water, you need more than one of these. I currently use one blue and two whites on my 20 gallons and changing the white to a blue hasn't changed the color of the tank much. I can try adding Color Max or Beauty Max and maybe that will help. Or maybe two blue ones and one white. This cheap device is getting more and more expensive. Blue is good, but don't expect it to give you a reef look on its own. Too bad Aqueon isn't more informative about the four colors of lightbulbs. Wouldn't want to be wrong again if the price was $20 each.
