I did not cycle my 55 gallon tank and threw 12 exodons and 2 pictus cats in it. Ammonia levels were fine for days. They are currently at 3.0 ppm with no signs of nitrite and I have not checked for nitrate because I doubt there is any sign of it. I will be doing a 50 percent water change today to see how the results are. Into the 10th day of the cycle today. Everything looks healthy but I think health problems are on the horizon.
