Upgraded one of my tanks last weekend from 37g to 60g. Moved all of the old water to the new tank. Moved an AQ 50, AQ 70, and AQ 110 to the new tank without changing are cleaning any media. Moved all decorations and rocks also. The only thing that is new is the subtraight. My last water test in the 37g was ammonia 0.0ppm, nitrite 0.0ppm, and nitrate 10ppm. I've tested the water in the 60g everyday this week and its been ammonia 1.0ppm, nitrite 0.0ppm and nitrate 10ppm(today its 20ppm). My question is why am I not showing any nitrites? Is my new tank cycled? Everytime i've ever upgraded a tank the cycle started all over just quicker. Please advise.
