I'm looking for a new fixture, mine is getting to old, and I'm planning on getting T5 lights. I currently have soft and sps corals, and I'm running PC+150watt Halide. My tank is 16" tall, 36" long. Any recommendations? My sps corals are at the top(5inches under water). Could I get away with 2 bulb fixture, or should I go with a 4 bulb? Also, has anyone ever tried Odyssey? They're sold on ebay.
