If it's regular old aquarium gravel, then you'll probably want to go get something that's better suited for planted tanks. You want something with small granule size, without being too fine like dust. Playsand is a good, inexpensive option which can be purchased from any Home Depot or Walmart. Other (better) options are to use Eco-Complete, Fluorite, or Aquasoil.
In a small tank like the jbj, trust me, you'll want smaller granules for your substrate. Good luck to you, and make sure you take plenty of pictures!
