I got my tank about 3 months ago used. Before that the same tank with the same rock, live sand, etc. had been going for over a year. Within the past month I have begun to get a lot of hair algae and my water quality is perfect and my lights are only on for 7 hrs a day. I have over 100 snails/crabs and they are munching on it now, but am wondering how often I should replace my lights, because I don't know how long the previous owner had the lights.
I have a corallife 48" pro with lunar lamps, double ended metal halides, blue actinic compact fluorescents. If I should replace them, should I replace all of them or only one type of the lights? How often in the future?
