Exo-Terra BioDrain Terrarium Draining Substrate is a natural, non-decomposable substrate that facilitates healthy drainage in your reptile habitat, without decomposing like organic substrates. It also functions as a biological filtration system, allowing water to be recirculated for use in waterfalls and drippers.

  • Natural non-decomposable crushed lava substrate
  • Creates a water drainage system
  • Provides medium for biological filtration
  • Ideal for tropical terrariums & paludariums

Optional: Use with Exo-Terra BioDrain Terrarium Draining Mesh to keep BioDrain substrate separated from decorative top-layer substrate.

Note: For enhanced biological filtration, use with Exo-Terra Bio Clean (formerly known as Biotize).
