You know they say when you assume, you make an A** out of U and ME. I started a thread yesterday asking about lighting, but I think I may be confused on exactly what LPS, SPS, and softies really are. I know what the acronyms stand for, but I always assumed LPS and SPS were the corals that look like they hard to the touch and are branching. But I read somewhere today that zoos are an LPS.(?) What actually characterizes the different types of corals? Just when I think I'm getting somewhere I realize I was dumber than I thought(does that make sense?)lol...
