Right now i have a 260W PC fixture on my 120g. Originally i was planning on A FOWLR, but i am beginning to want a full reef. I know that 230W on this tank isn't enough for corals, but a friend of mine has a 150W Halide pendant that he is selling and i am thinking of buying it. My question is... As far as lighting goes is 150W from a halide lamp different than 150W from PC or T5 lighting? I think its pretty much agreed upon that halide lighting is the best, but is this because it is stronger or is a Watt a Watt regardless of what kind of bulb is putting it out? And finally is it worth it for me to buy the one 150W halide pendant for my 120g. I only want to keep soft stuff like leather, shrooms, and soft polyps.
