    if i add everything from my 12 gallong tank, including gravel, plants decorations and water into the 40 gallon tank, will i get an instant cycle...or it the 12 gallon media not enough?

    You will get an instant cycle if you feed the bacteria and could add fish right away. But you may need to get more gravel if you do not have enough.

    yeah i bought some more gravel, and i'm planning on adding the fish from my 12 gallon tank to the new forty....

    If you add all the filter media from your 12G, and add more media for more bacteria to grow on, then you should be right.

    The media (b/b colony) in your 12G are coping with the population so that shouldn't change.

    I also agree on adding some more gravel for even more b/b to grab onto.

    I'd give it a week or 2, just to let everything settle, and to give your community a chance to adapt to their new home, establish territories, and just get comfortable.

    As for the filter, and the rate of introduction, I'd only introduce a few at a time to give the bb colony a chance to adapt and grow to cater for the new bio-loads.
