I've been out of the hobby for several years. I have a 40 gallon breeder and I'm thinking about investing in LED. I just don't have any clue which ones to get or which ones will be enough for my tank. I want to have the option of keeping any kind of corals. I'm not that much of a DIY kind of guy so that is out of the question. Also would 2 Koralia's 750 be enough for the tank? Thanks in advance.
