Re: Fishless cycle is just not working, guidance needed.... #21
I dosed ammonia to around 3ppm this morning at 7 am and I’ve just tested ammonia now and it’s reading as 0ppm, does that mean she is finally cycled?!

Re: Fishless cycle is just not working, guidance needed.... #23
I'm two weeks into trying to cycle this tank again, and I believe things are looking up but just wanted some further advice.

I'm not getting any kind of nitrite reading at all, but I'm having to redose the ammonia, and the nitrates are high all the time - at least 40ppm, and i've done three water changes over the last 3 days and the nitrate reading doesn't drop below that 40 level, so something must be happening. I always thought there would be some kind of nitrite reading though, rather than 0?

I've been using Microbe Lift - Special Blend, so if the cycle is happening I've got that to thank for it. I've also got a nitrate remover (Microbe Lift - Aqua Balance) that I'd like to add to the tank so I don't have to keep doing water changes but would it affect the cycle at all?

Re: Fishless cycle is just not working, guidance needed.... #24
A last update for this - I did a large water change to get rid of the ammonia, and used dechlorinator with the fresh water. I then redosed the ammonia to 2ppm; this morning the readings are 2ppm ammonia, 0 nitrite, 40 nitrate. I think it's pretty certain the cycle has stopped so I'm shutting it down because I need a break from it. I'll use the opportunity though to change the gravel to sand and completely change the decor.

Thanks for the help you gave with this Fishlady, appreciate it.

Yes I used dechlorinator, temp is 26 degrees and I’d say there is good oxygenation - I’m using a spray bar and it agitates the water surface well enough.

Re: Fishless cycle is just not working, guidance needed.... #26
Quick update - I've just tested the tank and ammonia is the same as it was 24 hours ago, so I think the cycle has definitely failed. The question I have, and I think I know the answer, is has the beneficial bacteria that has built up now died off?

I think my main issue here is that nitrates were severely high (in part due to me only doing a 50% water change when I last retried to kickstart the cycling process), so that affected the cycle and the test results. I'm also not sure dumping the whole bottle of beneficial bacteria into the tank was a smart move either.

Unless the bacteria is somehow still alive I will be shutting the tank down completely and starting again.

Re: Fishless cycle is just not working, guidance needed.... #27
I dosed it to roughly 2.5ppm so if it is being processed it’s incredibly slow.

Re: Fishless cycle is just not working, guidance needed.... #28
Quick update - I tested ammonia and nitrite just and ammonia is still showing I’d say between 1&2ppm, whereas nitrite is showing at 0ppm. Nitrite cannot be getting processed because the ammonia would have been consumed by now so has the cycle stalled?

Re: Fishless cycle is just not working, guidance needed.... #29
In the end I did a 40% water change, conditioned the water, then re dosed with ammonia. Today the ammonia levels don't seem to have dropped and nitrite still registers as 0ppm. I also did a nitrate test and that looks the same as it did before to be honest so I'm not sure what progress is being made, if any. It seems to be the slowest cycle in the history of tank cycling - a full 24 hours since I dosed the ammonia yet the bacteria don't seem to be consuming it for whatever reason.

Re: Fishless cycle is just not working, guidance needed.... #30
What would I do without your advice lol.

I've retested nitrate and got someone else to look at the results and they reckon it's 80ppm, would you still recommend a water change or leave it alone for now?
