organic soil without perlite or vermiculite. Also, if you are going to have anything natural in your setup ie:wood or vines, you have to prep them too. Fake vines can be treated with a mixture spray of vinegar, hydrogen peroxide and water, there are threads online that have the proper ratio recipe. Soil and natural sticks should be baked (on the forums they say to bake it like a pizza) for around 15-20 minutes (warning it will smell) we use a baking sheet. Cleaning of the sticks with the spray mixture should be done weekly/bi-weekly. Let them dry in the sun (or air dry) before putting them back into the tank.
