Weird...
 

I recently added two ice blue zebras to my aquarium. I came home a few
hours later and have noticed some kind of substance covering the
entire inside of my tank. It looks like little pinkish white lint...it
isn't ich, I've dealt with that before. I'm not sure what it is. I
have a 75 gal tank with an emporer 400 filter. I keep my water at 80
degrees. Am I doing something wrong?
