Exo Terra BioDrain
Terrarium Draining Substrate is a natural, non-organic substrate that allows
excellent drainage of the terrarium. It will not rot or decompose like other
natural substrates. The optional BioDrain Terrarium Draining Mesh will keep the
BioDrain Terrarium Draining Substrate separated from the decorative terrarium
top-layer substrate and prevent the different substrates from mixing and
contaminating the water.
The BioDrain Terrarium Draining Substrate will function as a biological filtration system. The clean terrarium water can then be circulated in waterfalls, the Exo Terra Rain System or Dripping Plants.
Use Bio Clean (formally known as Biotize) to speed up biological filtration capabilities.
