I am completely new to keeping fish. I have a Juwel Vision 260 aquarium and want to keep tropical fish. I am 36 days into a fish less cycle, adding ammonia each morning to 4ppm.
The ammonia has been dropping to 0, or 0.25, as have the nitrites, and the nitrates have been at 5, so yesterday I did a 90% water change, and added ammonia to 4ppm again.
This morning I am very confused as my readings are
Ammonia 0.5, Nitrite 0.5 but Nitrate 40.
I suddenly thought about the tap water I added yesterday. I tested that and it has a reading of Nitrates at 20 on its own.
I am not sure what to do next. I would really welcome any advice.
Thank you Irene
