Hi, I am currently preparing my first reef tank! I only need one last piece of equipment, the lights. My tank is 30 gallons and the dimensions are 30x13.5x18. I plan on getting a variety of different types of corals except for SPS (or not for a loooong time at least). I've gotten a little overwhelmed trying to buy the correct light. Can I please have some suggestions for a light that is good for a growing a variety of different corals and doesn't cost me $300?
