So my tank has been cycling for 2 weeks now and my readings are all showing zero. As I have been testing I got an ammonia spike, then nitrite, then nitrate. When I tested last on Friday my nitrites were up and everything else was zero, today everything was down to zero. Does this mean that my cycle is over. When cycling in the past it took over a month. Could it be because half of my rock came from an established tank?
