I have a JBJ 20g Cubey and it has 6 different lighting options. There are 4 different options of white (bright white, light yellowish white, and 2 other off white options). Then there is a blue and a red option as well. I have a stylaphora and a zoanthid in the tank. I usually just run the blue light for 9 hours a day and at night no light. I did this because I heard blue light was good for growing the algae needed for the corals. What would be recommended for what light to run? It is the lights that came with the tank and they are LED.
