If nitrite is also 0 then yes, at last!

Re: Fishless cycle is just not working, guidance needed.... #42
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?

If you've recently redosed it's to be expected. check again after 12 hours.

Re: Fishless cycle is just not working, guidance needed.... #44
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?

Re: Fishless cycle is just not working, guidance needed.... #45
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.... #47
Hard water isn't suitable for cardinals or for most tetras and they will be under permanent osmotic stress in alkaline conditions, leading to increased susceptibility to disease, liver and kidney problems and a shorter lifespan. However, there are a few tetras that can deal with harder water so you may want to consider these:

X-ray tetra - Pristella maxillaris
Congo tetra - Phenamogrammus interruptus
Black widow tetra - Gymnocorymbus ternetzi
False penguin tetra - Thayeria boehlkei
Red - eye tetra - Moenkhausia sanctaefilomenae
Glass bloodfin tetra - Prionobrama filigera
Lemon tetra - Hyphessobrycon pulchripinnis

Regarding nitrate remover: it shouldn't be necessary to use this kind of product. With the right stock level and a weekly 25-30% water change nitrate should be well-controlled.

Re: Fishless cycle is just not working, guidance needed.... #48
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.
