I have two tanks and I recently noticed that some of my Zoas started closing up and getting brown stuff over them. Has anyone had any experience with this before. I did some research and a lot of people point to doing a Furan-2 dip for them. I was curious to see who has dealt with this same problem and had success. I took a tooth brush to my Zoa to see if it would come off and it didn’t really do much.
