Another cycle question

My nitrites and nitrates finally spiked about a week and a half ago and have not gone back down yet. I was wandering if anyone could tell me how long it usually takes for them to drop back to normal?

Once your nitrite drop to 0 then you are done cycling. At that point you should have 0 AM, 0 NI, and some NA depending on how you cycled. At this point you should do a 15 percent change to get your NA down to a livable level, then you are ready for fish. DO NOT place all fish in at once, place one or two at a time to allow your bacteria to multiply with the bioload.
All in all, it takes ABOUT 3 weeks to cycle, some more, some less depending on how you cycled, tank size, etc.
