I had ick about a month ago and took all the fish out and put them in a hospital tank. My 85 gallon lf only was left empty during that time and some sort of brown stuff formed on the sand. when I tried to suck it up during a water change it looked like i got it all, but when it settled down it all settled on the bottom again. it is very hard to get out of the tank. since I put my surving fish a powder blue tang and a maroon clown back in the tank, they stir it up. anyone know what this is? Is it a problem? Is it alge?
