Hello! New reefer here with about a 9 week old tank. I put in some test corals a few weeks back and I noticed a red bacteria or algea (is this Cyano?) on a Zoa frag. It's only on the Zoa and and no where else in my tank (other coral , rock, or sand). Is there anything I can do to get rid of it / save the zoa? My nitrate levels are less than 5ppm but unable to provide phosphate level (will pick up a kit asap) Thanks in advanced.
Here is was when I first got it:
