When you want to seed your tank with springtails there is a couple ways this can be done. Place a piece of fruit or vegetable on top of the soil in the springtail culture overnight. The next morning the piece of fruit should be covered in springtails. Hold that piece of fruit over top of the vivarium and blow gently. This will cause the springtails to fall into the tank. Another way of doing this is to take some of the soil from the springtail culture and place it directly into the vivarium.  

If you have provided enough leave litter and places to hide then springtails will start producing in your tank. If your springtail culture is made with charcoal and easy way to get them out is to flood the culture. By adding water to the culture the spring tails will float to the top. Using your hand or the culture lid hold back the charcoal and dump the water into the vivarium. Leaving the charcoal in the container will ensure that some springtails stay in the culture and continue to reproduce.
