I thought I cycled my tank by putting stress enzyme and stress coat rounds in the aquarium for a month before adding 3 oscars to my 30g tank. I took a water sample to the LFS before adding fish. (No I'm not going to keep them in that tank) I am now concerned as my water is a little cloudy and I have learned I really didn't cycle my tank at all. My fish have been in there for 15days and I didn't see a problem until last night when I came home and one Oscar was floating. I thought he was dead so I went to scoop him up and he perked up a little. He is now back to normal swimming, eating and bullying. However the other two fish seem to have what looks like white spot to me. I did a strip test my pH is 7.2 hardness is 120 and nitrate/nitrite is 0 ). I have added another air stone, liquid cycle, and tap water conditioner. My water temp is 82. I have not changed the water yet as I don't want to mess with anything else until I get at least two of the same answers. Change the water leave it alone. Add salt just do a water change. Someone please help me!!!
