I am new to "lights" since I never had a reef tank. I want to start adding corals to my tank but I know I need different lights. To my knowledge there are Metal Halides, VHO, PC & T5. What are the differences in all these different lights. I know it's a complictaed topic but I need help before I go out and buy them. I want to basically be able to have any coral except for SPS COrals because I hear they are very hard to keep and need very big tanks. I currently have a 90 gallon FOWLR.
