No, I agree! I was really surprised to see nitrates that quickly. I had had the tank up with plants for about a week before I started cycling, and three weeks after that before I got my fish (the tank was able to cycle out about 2ppm of ammonia all the way to nitrates in 24 hours... I dilly-dallied for a week, then brought home a betta with damaged fins from Walmart).
My record is a little sketchy because 9 days of the cycle I was out of town, and had left my roomie with instructions to add ammonia each day. I expected the tank to have crashed while I was away simply because I had no idea what I was doing. lol
I've been checking the water parameters every 1-2 days with my fish in there because I'm afraid it hasn't cycled all the way. 7 days later, ammonia and nitrite are still at zero, nitrate is less than 5ppm.
