Do another water change before bed. This should bring the ammonia down below 2. Do another tommorow morning, ect. Test every 12 hrs for ammonia, nitrite, nitrate. Now that you have added media (sponge, floss, what?) from another tank, you should begin to see the numbers change. Ammonia 0, nitrite 0, nitrate >5 is the goal. When this happens the cycle is over and you are good to go.
