Well, sadly there is one issue. The coral you are keeping will require more light than those marinelands put out. Them being reef capable is a straight lie. I've watched my LFS
buy into them, saying they worked, and literally murder coral they have had in their store for years. Was very sad. If you are looking at keeping this type of lps
coral, you should look into investing in a smaller t5ho unit, something that puts out more lighting. Luckily for you, duncans are very hardy coral and should do well even if the parameters aren't perfect.
