The Exo Terra BioDrain Terrarium Draining Mesh is part of the BioDrain Terrarium Draining System. The non-toxic mesh will keep the underlying Draining Substrate separated from the decorative terrarium top-layer substrate. It also allows proper water drainage when used in combination with the BioDrain Terrarium Draining Substrate, as the BioDrain Terrarium Draining Mesh prevents contamination of the water by decorative substrate particles. It is ideal to create water parts and a biological filtration system in the terrarium using the Exo Terra BioDrain Terrarium Draining Substrate. The clean terrarium water can then be circulated.

BioDrain Terrarium Draining Mesh Medium (PT3133) fits Natural Terrarium Medium (PT2604, PT2610, PT2612 & PT2608). For bigger terrarium surfaces (e.g. Natural Terrarium Large PT2613, PT2614 or PT2609) combine multiple pieces of BioDrain Terrarium Draining Mesh.

• Non-toxic non-decomposable liner
• Create a water drainage system
• Separates the BioDrain Terrarium Draining Substrate from decorative substrates
• Prevents substrates from contaminating the water

The Exo Terra Bio Drain Terrarium Draining Mesh is part of the Bio Drain Terrarium Draining System. The non-toxic mesh will separate the underlying Bio Drain Draining Substrate from the decorative top-layer substrate. It will prevent substrate particles from contaminating the water while allowing proper water drainage. Combined with the Bio Drain Substrate, you can create water parts and a biological filtration system in the terrarium. The clean terrarium water can then be circulated in Waterfalls, Cascades or Dripping Plants.

How to install Bio Drain:An example of a layered substrate in the terrarium using the Exo Terra Bio Drain Substrate and Bio Drain Mesh:

1. Place the Natural Terrarium on an even surface and clean the waterproof bottom part.
2. Wash the Bio Drain Terrarium Draining Substrate thoroughly and spread it evenly in the terrarium.
3. removing the substrate in the desired location creates a water part.
4. Cover the Terrarium Draining Substrate with Bio Drain Terrarium Mesh, and separate the water section with moss, bark or rocks
5. Add a biological substrate like Plantation Soil on the terrestrial (land) area.
6. Plant your live plants, mosses & ferns and cover the top soil layer with leaf litter.
7. Live plants provide shelter, retain moisture, yield nutrients for various organisms, and absorb ammonium and nitrates in the soil.
8. Add an aquatic substrate like Turtle Pebbles or Riverbed Sand to the water part and add water.

Since both the BioDrain Mesh and Substrate are non-organic, they will not rot or decompose.

Use Turtle Clean (PT1998 or PT1999) to add beneficial organisms to the terrarium water and speed up biological filtration capabilities.

Exo Terra Plantation Soil, Terrarium Moss, Jungle Earth, etc., can be decorative top-layer substrates.

For larger terrarium surfaces (e.g. Natural Terrarium PT2613, PT2614 or PT2609), combine multiple pieces of BioDrain Terrarium Draining Mesh.
