Okay, this may sound crazy, or worse, stupid, but I do not have a sump, or refugium, so I am thinking about putting some macro algae in my display tank, for 2 reasons. 1) all the benefits, and 2) I think my Naso tang and my foxface would love munching on it. Any and all thoughts on this welcome! I know absolutely nothing about macro algae, other than it is beneficial to keeping down nutrients and phosphates.
