Hello, I recently downgraded to a 30 gallon long and I'm still debating lighting options. I had halides over my previous reef and my SPS loved them. However, I'm looking at T-5's for my new tank. Is it possible to house SPS under a 4 bulb T-5 fixture, or will I need to go with a 6 bulb? Thanks in advance.
