I just lost half my fish. Last night before bed I was admiring them at how much they have grown and their beautiful colours and this morning I am mopping up the dead ones. Fish still alive appear to be breathing heavily.
Doing a big water change and added an air stone in tank. I have a heavily planted non CO2 tank. My feeding and plant dosage regime has been the same the last 12 months. I only do a 30 % water change once a month.
I have SENEYE monitoring system. pH 6.96, ammonia 0.001 ppm. Nitrates about 10ppm using test kit but nitrites are 0.5ppm.
Last night before I went to bed I dosed the tank with the weekly Seachem Iron, Flourish and Excel at normal dose. I used a new bottle of Excel. I have a canister filter that is cleaned every 3 months but sponge cleaned monthly.
So I would dearly love to know what caused my nitrites to spike?
Also why did nitrites spike in the absence of an ammonia spike? How can this be explained?
Bewildered and numb from the loss.
