    I just purchased my first aquarium. It will be a 20 gallon freshwater aquarium. My question is i have a filter on an established tank already and i was wondering once I place that filter in my tank how long will the bacteria live without being feed ammonia from fish or any other source? Thank you and this website is very helpful.

    Hi welcome to FishLore :)
    I'm not sure how long the bacteria can live without a source of ammonia.
    Personally, I would think the bacteria would begin to die off in a few hours and def. would start to worry about losing the cycle after a day. That's just opinion, not fact.

    It'll be interesting to see if someone knows for sure.

    Welcome to fishlore! I would think that the bacterial colony would die off pretty quickly with no ammonia source at all... maybe 24-48 hours? This is just an educated guess, though.

    That would be an interesting experiment to test out... however without a source of ammonia the bacteria wouldn't last long. 48 would be the max I think before the bacteria population would be too small to handle even a light bioload... Assuming that the media is kept wet during the time...
