Re: Fishless cycle is just not working, guidance needed.... #1
That is disappointing I must say though Congo terra and lemon tetra do appeal to me so I’ll see what’s available. I’ll keep an eye on nitrates as the tank beds in and see what happens.

Thanks again.

Yes, that will be fine. Bacteria can survive a couple of days in a tank with the filter running, and several hours without running water. Congratulations, and enjoy your fish


Thanks for all your help with this it feels like it's taken months and months!

I do have a couple more questions I will throw your way though.

At what point do I begin using the nitrate remover? The bottle states to use an initial dosage for four weeks but do I aim to start using it once nitrates reach a specific level?

Thinking about the livestock I will have in there has proved tough because our water here is hard but I like tetras. I know a lot of tropical fish are tank bred nowadays and cardinals were the last fish I kept along with platy and I really liked the tetra. Are they suited long term to the water and, if so, what makes a suitable tank mate for them other than more cardinal tetra?

Thanks.

Re: Fishless cycle is just not working, guidance needed.... #3
Ok test results this morning are ammonia 0, nitrite 0, nitrate 160ppm.

Rejoice!

I’ve done a water change and have redosed the tank with ammonia, which I will have to keep doing until Wednesday because that’s the earliest I can get the tank stocked.

How long can the bacteria survive without ammonia? Thinking about the logistics of it all; I’ll be getting fish roughly Wednesday afternoon but the last dose of ammonia will be going in Tuesday evening so will that suffice?

I’ve just done a nitrite test and that is reading as 0.25ppm, but I’ve not long added another dose of ammonia so what does that mean?

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.... #7
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.... #8
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.... #10
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.
