Quick NitrIte question

[brianriv]

After a tank is cycled what can be the cause of a nitrIte spike?


The only things I have done are add 2 baby Bristlenose about a week ago and about 10lbs of new gravel. I am doing a water change as I type this message. Hopefully the reading will go down some. Thanks

the new gravel might have an effect as this doesn't contain any good bacteria and might affect the bacteria thats in the original gravel

Thanks for the quick response. That is what I thought would happen too. Before I added the new gravel I had posted a question about it and was told that there shouldn't be any ill affects from adding new gravel, but maybe there is. Well I did the water change and the nitrItes went down. I guess I will just keep track of it for the next few days.
