So I have this algae that starts growing on the glass, then in the sand. It just spread onto my on frag rack and now onto my zoa frag. That’s the first time it’s grown onto a coral. I can clean the glass spotless and it comes back within a couple days. What is it and how do I get rid of it? Also how do I save my zoa frag? Is there a dip that will get rid of the algae?
