Exo-Terra BioDrain Terrarium Draining Substrate - 4.4 lb

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).
