I am wanting to have a blue light and a normal light on my tank. Are there hoods that house both of these lights? Does this make any sense at all?!? I want to be able to turn my blue lights on in the morning, then my normal daytime lighting, then in the evening turn the blue lights back on for a while before I turn the lights out for the day. I can't seem to find anything online, but I don't really know where to look or what to search for. Help please!
