Fishless Cycle 1 Week Ahead Of Me

Don't top up the ammonia.
 
Only give the bacs a 'snack' of 1/3 of normal dosage when you get 2 consecutive readings of 0 for ammonia every 48 hours. And only one 'snack' should be needed.
 
And yes, this will take a few weeks before you will be fully cycled, but you arel on the way now :)
 
Quoted from the fishless cycling article - 
 
If at any time after the first ammonia addition (Dose #1) you test and ammonia is under .75 ppm and nitrite is clearly over 2 ppm, it is time to add more ammonia (Dose #2). Add the same full amount as you did the first time. Now, begin to test the ammonia and nitrite levels every other day. (You should be seeing nitrate soon if you have the kit.)
 
 After the second ammonia addition (Dose #2), while waiting for nitrite to rise, peak and drop, the bacteria will need a maintenance feeding (Dose #3). Give the bacteria a “snack” by adding 1/3 of the full dose when you get two consecutive every other day ammonia test readings of 0 ppm,. This “snack” (Dose #3) should be needed somewhere between days 21 and 27 of the cycle. Only a single snack dose is needed.
 
If at any time after the first ammonia addition (Dose #1) you test and ammonia is under .75 ppm and nitrite is clearly over 2 ppm, it is time to add more ammonia (Dose #2). Add the same full amount as you did the first time

This is my situation
 
Yes, but you only do this once, THEN once you get 2 consecutive readings of 0 for ammonia after 48 hours tests, you then can dose a snack of 1ppm ammonia, again this is just once.
 
Adding too much ammonia or too often can result in problems / cycling issues.
 
Today is my second dose , now after this I'm onto the snacking right ? So today is one more full dose and then when I get the 0 readings I begin to feed 1/3 of the dose. Shouldn't be long judging by my results so far.
I've already put the second dose in about half an hour ago ....
 
Sounds about right. It does sound like the media you put into the new filter had some colonies left. Hopefully this cycle will take less than 6-8 weeks for it to be completed. however, I am sure someone on here once told me that if the nitrate reading reaches 160ppm it can halt the cycle and put the bacteria into hibernation. Someone else will let me know if I am wrong though good luck
 
It looks like the nitrites are starting to drop so I'm confident it hasn't stalled at the moment, tonight's testing will give me a better idea. Either way its looking to be a shorter than average cycle I think. Thanks for advice
 
Nitrites dropped from 1ppm yesterday to 0ppm today. Should I dose 3ppm and see how it drops ?
 
If ammonia at 0 as well yes, full 3ppm dose of ammonia, see what result is in 24 hours.
 
Getting there , ammonia dropped to 0"in 24h but about 1ppm nitrite still hanging around
 
That's about where I was near the end of my cycle. Unfortunately now is the time when patience is really required, because for some reason (in my experience) the last step of getting 0 nitrite in 24 hours took what felt like forever!
