My ammonia levels are still at 8.0 even with a 75% water change yesterday and today. I have noticed my first signs of fish stress. 4 of my fish were all rubbing against the air line tubing and "flickering" (not sure what you call it) off it. I just turned on their lights for the day and noticed that my molly has 3 white spots on his tail. I just did some quick research and it sounds like ich. Its always something! Is quick cure safe for african dwarf frogs? Also a couple of my fish look pale, would this also be from the ich? I ran out of prime yesterday, so I don't know what Im going to do now about this ammonia.
