False bottom (also known as LECA, for light expanded clay aggregate) is a great choice for the drainage layer in a vivarium. LECA is a natural product, made from heated clay. It retains moisture, provides lots of surface area for bacteria and plant roots to grow, and wicks water, which will help maintain humidity in a vivarium. * This product can range in color from burnt orange to dark brown, almost black. *     How to Use: Rinse with dechlorinated tap water before use. Place a 2-3 inch layer as the drainage layer in a vivarium. Designed to be used with our substrate barrier and ABG to provide ideal vivarium conditions for tropical plants and dart frogs.     Warnings/Caution: Rinse before use. May contain dust.
