Hello, I have no idea what is going on in my tank. The tank has been set up for a couple of years. Running well. Now all of a sudden most of my fish has this gunk on there eyes. Lost a Purple Tang last night.. The water parameters etc are fine and I have not done anything different than normal. Please help... Thanks
