starting tank cycle without a heater

I'm guessing Jeff misunderstood the OP statement regarding media and was thinking water instead of filter media. Jeff?

Of course seeding a new filter with old media from an established tank jump starts the cycle as a colony or portion thereof is simply being transferred. (Just need to ensure an ammonia source is also furnished to continue to feed the crew).

Also I once saw an interesting youtube entitled 'instant cycle'. Operators of a fish store demonstrated 'instant cycle'...they squeezed clean a sponge filter from an established tank in a cup of water that quickly turned almost black. They added this to the filter of a new tank setup. Really similar to adding a bacteria supplement, but from a known fresh source.
