Since I'm new to the hobby, I was wondering if I really need a metal halide for my tank. Let me explain, I have a 125gal reef tank and it has a lot of different kinds of mushrooms. Some of which are umbrella and the regular and was wondering if a metal halide is required? I do have 2-actinic VHO 6' long and definitely think it's enough. I also have a Iwasaki 65K metal halide but I don't think anything in the tank requires it. I also think that it's a contributing factor for hair algae propegation. What's your take?
