Compared to gravel, Expanded Clay offers the aquaponic gardener many advantages.

expanded clay
  • 1/2 the weight of gravel
  • The ideal round shape is easy on hands
  • Completely inert, pH neutral and does not contain any nutrient (gravel can contain toxic or pH altering materials)
  • Porosity creates excellent air and water exchange
  • 8-16mm range size.

Orders of more than 4, 50-liter bags

Because the larger bags are so bulky and heavy, they can be expensive to ship. That is the bad news. The good news is that we work with two distributors with multiple locations around the U.S. that they ship from to keep shipping costs as low as possible.

If you order 1 - 4 large bags, we've found that it is cost effective to ship via our normal carriers. If you order more than 4 bags, however, it is generally less expensive to ship via freight from one of these distribution centers. Our ecommerce system can't do this automatically, so it will look like you received free shipping when you check out. We will get back to you with a freight quote after your order has been placed.
