This is a true beginner question (Actually just about every question I ask here is a true beginner question). I have a corner tank and am having some trouble figuring out how to get a light on it. When the product advertisement says "18 inches" Does it mean that the bulb is 18 inches or that the fixture all together is 18 inches.
I am looking at Coralife
PC lighting, the size depends on the answer to the above question, either 18 or 24 inches. If the lights stand on legs how can I get them to fit my corner tank? Can they be adjusted?
Thanks.
P.S. I almost put this in the "New to Saltwater" section, but since this is pertaining to lighting I put it here.
