Introducing the BIO DRAIN MEDIUM Terrarium Draining Mesh, a non-toxic, non-decomposable liner that forms an integral part of the Bio Drain Terrarium Draining System. This mesh is designed to keep the underlying Bio Drain Draining Substrate separate from the decorative top-layer substrate, preventing substrate particles from contaminating the water while still allowing proper water drainage.

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, creating a vibrant and healthy environment for your terrarium inhabitants.

Installation of Bio Drain is straightforward:

• Place the Natural Terrarium on an even surface and clean the waterproof bottom part.
• 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.
• Cover the Terrarium Draining Substrate with Bio Drain Terrarium Mesh, and separate the water section with moss, bark or rocks.
• Add a biological substrate like Plantation Soil on the terrestrial (land) area.
• Plant your live plants, mosses & ferns and cover the top soil layer with leaf litter.
• Live plants provide shelter, retain moisture and yield nutrients for various organisms but they also absorb ammonium and nitrates in the soil.
• Add an aquatic substrate like Turtle Pebbles or Riverbed Sand to the water part and add water.

Both the BioDrain Mesh and Substrate are non-organic, ensuring they will not rot or decompose. For larger terrarium surfaces combine multiple pieces of BioDrain Terrarium Draining Mesh.
