I'm wondering roughly how long from the time you collect it, the bacteria will survive in a piece of mature filter sponge. I've added mature media to my filter with no signs of it helping my cycling process. It took me about an hour to get it home
As long as it did not dry out, it's fine. There aren't as many studies on the bacteria that eats nitrite, but the bacteria that eats ammonia for example can live for MONTHS without food (there have been several science studies and papers written on this).
Did you put it in your filter touching your new media (this is the most effective way)
When was this?
What were your readings then and now?
You don't have to answer all the questions, it just seems like you need more assistance
I am not 100% sure since a canister is a fairly closed environment, and one thing that they do need is oxygen as they are entirely aerobic. There is evidence that the nitrospira (nitrate-nitrate BB) are better adapted to a low oxygen environment, but the nitrosomonas (ammonia-nitrite BB) are definitely aerobic. (source from various papers I read) It wasn't clear to me if a lack of oxygen causes them to go dormant, or actually causes them to die.Can I ask what about if sitting in a canister filter not running? A few days I gather at least perhaps?
I did put the media touching the existing media, this was a week ago. It's hard for me to keep track of my readings I test my water everyday and its always around 0.5ppm amm no nitrite. I do 30/50% water changes everyday. Should I stop doing water changes so frequently? I knew nothing about cycling when I started out so I've got 4 juvenile angels and some corys all stuck in a fish in cycle. Should I try and return them? I really don't want them to be harmed by my ignorance

So - I'm not quite sure. I'm not sure how much oxygen they NEED, like perhaps the amount left saturating the water is enough for a few days, but maybe not.
Inconclusive! Sorry
