ok some zoos in my tank have been closed for about 1 month. Then algae started growing on polyp itself. Almost like cyano bacteria. Then they started rotting and falling off colony. Weird part is i have lots of zoos in my tank.. This particular zoo is in two parts of my tank on seperate sides. However both sets of zoos have this happening. I have done lugols dip and all my params are in good order . any ideas?
