    How long should I leave my new uncycled sponges in my sump before putting them in service in my new tanks?

    It won’t do anything unless your bioload is above your current filtration capacity. There won’t be bb on it unless there’s enough ammonia to feed the bacteria. If your tank is already cycled then there’s no more ammonia to feed new bacteria

    So you're telling me that I'll get zero bacteria on my sponges? That contradicts everything I've ever read.

    If what you're saying is correct, then theoretically all I need to do is overfeed my fish. If so, how long?

    It'll take about 4-6 weeks if you don't have an airstone in the filter for flow. With an airstone, 2-4 weeks.

    Does More Media Always Equal More Bacteria? Read this. I’m not sure how long but overfeeding your fish isn’t a good idea

    You link a thread of your own to support your own comment? And with only 2 responses and now it's gospel? Really????

    Not to support my own comment but to inform that no ammonia equals 0 bacteria on another piece of media if your tank is cycled. Let’s not start an argument here

    I'm gonna give it another week and put the new sponge and some fish in.

    I appreciate the input, but I dont believe that adding the sponges to an established tank won't allow any bacteria to colonize.

    I understand the theory you're using. But who's to say that the bacteria to ammonia ratio is perfect? To believe I've achieved 100% homeostasis is a long shot.

    Maybe the OP wasn't clear but from my understanding, he has an established tank with a sump. He wants to put a new sponge filter in the sump to cycle it for a new tank he's planning on setting up. BB will grow on every surface water touches so it will seed the new sponge but slowly w/o water flow thru the pores.

    Agree with your understanding. A little bit of bb might grow but most likely not enough to cycle another tank. The op will still have to grow enough bacteria to support the bioload of all the fish in the new tank even if you got some bb from a cycled tank

    You're right. I wasnt really clear that it's an established system I'm placing the media in.
