If the media is being posted then the bacteria will most likely die anyway.
What you can do is ask your LFS or someone with an established tank to squeeze out the filter media into a jug or bag then within an hour soak/drench your filter media in this then get it running in the tank, i use this method and i was cycled within 10 days.
?, Can i add a hardy fish to cycle my tank? and if so whats best ?
