I'll use my fishless cycle from last year as an example
Day 1 - added ammonia
Stage #1Day 4 - no change
Day 7 - no change
Day 10 - no change
Day 13 - no change
Day 16 - ammonia still same but just a hint of nitrite though still well below 0.25
Day 19 - same as day 16
Day 21 - ammonia still showing between 1 and 2 and nitrite the merest hint. Got frustrated and did a 100% water change then added ammonia to give a reading between 2 and 4 ppm.
Day 24 - ammonia between 1 and 2, nitrite 0. The ammonia dropped from 2 - 4 to 1 -2 but no idea where it went.
Day 26 - tested after 2 days because getting fed up. Ammonia 1 to 2. Nitrite merest hint.
Day 28 - ammonia 0.5 nitrite > 5 (off the top of the chart). Added ammonia to ~ 3ppm
Stage #6Day 30 - ammonia 0, nitrite >5
Day 32 - ammonia 0, nitrite >5. Zero ammonia on 2 test 2 days apart, added the one third dose of ammonia.
Stage #8Day 34 - ammonia 0, nitrite >5
Day 36 - ammonia 0, nitrite >5. Zero ammonia in 2 tests 2 day apart, added the one third dose of ammonia
Stage #8 againDay 38 - ammonia 0, nitrite >5
Day 40 - ammonia 0, nitrite >5. Zero ammonia on 2 tests 2 days apart, added a one third dose of ammonia.
Stage #8 againDay 42 - ammonia 0, nitrite 0. Added a 2 to 4 ppm dose ammonia
Stage #10Day 43 - ammonia 0.25, nitrite 1.0
Day 44 - ammonia 0, nitrite 0. Added 2 to 4 ppm ammonia.
Stage #10 again Then power went off for 4 hours.
Day 45 - ammonia 0, nitrite 2 - was the cycle affected by the power cut?
Day 46 - ammonia 0, nitrite 0. Added ammonia to 2 to 4 ppm
Stage #10 again
Day 47 - ammonia 0, nitrite between 0.5 and 1. Added ammonia to between 2 and 4 ppm
Stage #10 yet againDay 48 - ammonia 0, nitrite 0.
Finally stage #14Ignore the dose of ammonia added on day 21 - I only added that because I removed all the water from the tank and replaced it with all new water so I had to replace the ammonia I'd put in on day 1.
On day 28 ammonia had finally dropped to below 0.75 and nitrite was over 2.0 so I added the second 3 ppm dose of ammonia and continued testing every two days.
On day 30 I had zero ammonia and nitrite over 1 for the first time.
On day 32 I had zero ammonia and nitrite over 1 for the second time so I added a 1 ppm dose of ammonia and continued testing every 2 days.
Zero ammonia and nitrite over 1 on days 34 and 36 so added another 1ppm dose of ammonia and continued testing every two days.
Zero ammonia and nitrite over 1 on days 38 and 40 so added another 1 ppm dose of ammonia. Continued testing every 2 days.
Day 42 finally had ammonia below 0.25 and nitrite below 1.0. Added a 3 ppm dose of ammonia and started testing every day.
Day 43 - both above zero. Test again next day.
Day 44 - both zero so added another 3 ppm dose of ammonia.
Unfortunately we then had a power cut in the afternoon of day 44 which seemed to affect the cycle, so it didn't follow a nice pattern from here, but you can see the pattern for the last few days of the cycle.
Just continue as my cycle from day 42 to day 44 until you get zero ammonia and zero nitrite 24 hours after adding 3 ppm ammonia.
Does this help
