Do I just got a prime 16HD for my 30 gallon tank and I’m wondering if any of you have this what setting you keep it on? I am not going for massive coral growth I j am most likely going to keep Green star polyps, frogspawn and a hammer. Maybe a leather, or anemone. I am totally up to suggestions on types of coral as well. Preferably no super expensive ones though. Thank youyour help.
