Reptile BioDrain Terrarium Substrate

• Natural, non-decomposable substrate
• Creates a water drainage system
• Ideal for tropical terrariums & paludariums

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.

• Wash the Bio Drain Terrarium Draining Substrate thoroughly and spread it evenly in the terrarium.
• Create a water part by removing substrate in the desired location, then cover the substrate entirely with the Bio Drain Terrarium Draining Mesh.
• Add a biological substrate like Plantation Soil on the terrestrial (land) area.
• Add an aquatic substrate like Turtle Pebbles or Riverbed Sand to the water part and add water.
