I think I am about ready to add corals into my tank.I have to admit I am a little confused about what will work in a pc lighted tank. I have 4 65 watt lights in a 45 gallon tank.I know I can keep softies which is a sps.. and I think i can keep some lps?Is frog spawn and torch corals, hard corals? I have a book that list all the corals but lps aren't mentioned. I am sorry to be asking so many questions but everyone here seems to have alot of experiance and I really have made enough mistakes already to have paid for an awsome set up.I also know corals are very intensive. Lighting placement water flow food. So any help would be great.
