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.

Even though you have 3 filters I would think a little ammonia spike is normal since you removed your original substrate. The 3 filters may be able to hold the bio load steady enough that you only got a small ammonia spike only. That's just a guess. You still may get a little nitrite spike. But with you using everything except your substrate from your old tank you would not be starting the cycling from scratch.

did you keep your filter media wet in tank water?
I would feed light and do a pwc

It often happens that there is a bit of disruption when we do major changes. This is when I like to have a box of ammo-carb or ammo chips on hand to do a temp job of soaking up some ammonia. I keep a small net bag and fill it with the chips and hang it in the output of a filter where the water flows through it. It is cheap and easy to take some of the strain off while things settle down to normal. One can soak the chips and reuse if it feels right but I usually just go for new at the price.
