I'm confused on lighting. I know light consist of color spectrum. Depending what color a bulb has will give you the color outcome. I know that corals need actinic bulbs. My fixture holds 7 bulbs. How many should I have? Also I really have no idea how you decide on the others. To me they all look the same. I bought some different ones and I see no difference. Am I missing something? The more I read the more I'm getting confused.
