How to install Bio Drain
An example of a layered substrate in the terrarium using the Exo Terra Biodrain Substrate and Biodrain 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. Create a water part by removing substrate in the desired location.
4. Trim the Bio Drain Mesh to perfectly match the interior dimensions of your terrarium.
5. Cover the Terrarium Draining Substrate with the mesh, and separate the water section with moss, bark or rocks…
6. Add a biological substrate like Plantation Soil on the terrestrial (land) area.
7. Plant your live plants, mosses & ferns and cover the top soil layer with leaf litter.
8. Live plants provide shelter, retain moisture and yield nutrients for various organisms but they also absorb ammonium and nitrates in the soil.
9. Add an aquatic substrate like Turtle Pebbles or Riverbed Sand to the water part and add water.

Both the Substrate Mesh and the Draining Substrate are non-organic, and 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, Forest Moss, Jungle Earth, etc. can be used as decorative top-layer substrates.

The Exo Terra® Bio Drain Terrarium Draining Mesh is an essential part of the innovative Bio Drain Terrarium Draining System. Crafted from non-toxic, non-decomposable materials, this mesh plays a vital role in maintaining a clear separation between the Bio Drain Draining Substrate and the decorative top layer. By preventing substrate particles from contaminating the water while ensuring proper drainage, it helps create a clean and efficient ecosystem within your terrarium.

When used with the Bio Drain Substrate, this system allows you to design stunning water features and establish a natural filtration process. The filtered water can then be seamlessly circulated through waterfalls, cascades, or dripping plants, enhancing the terrarium’s functionality and visual appeal.

The 90 x 45 cm or 35 in. x 17.5 in. cut-to-fit design ensures versatile and hassle-free installation for a wide range of applications.
