this is what would be considered SUPER low light, mushrooms maybe not much else, if your going to run Regular output flourescents your better off buying one actinic bulb and one 10k they are more efficient than the 50/50 bulbs are, but i would reccomend an upgrade to a better lighting system if you plan on keeping corals.
