Is my tank cycled.....

Subject: Is my tank cycled.....

Evening everyone.

I'm having a mental block and reading conflicting advice - I'm nearing the end of a fish less cycle but it's been years since I did this and I can't recall:

24hrs after dosing 3ppm ammonia I'm reading Ammonia 0 Nitrite 0. 12 hours after dosing Ammonia 0 Nitrite 2ppm.

I've had the nitrite spike and drop and showing plenty of nitrates - does the filter need to be processing the Nitrites to 0 within 12 hours or 24 for the cycle to be completed? I've had these readings for a week now.

Any help much appreciated!
