Exo Terra Bio Drain Substrate 2KG

Introduction

Exo Terra BioDrain Terrarium Draining Substrate is a natural, inorganic bedrock specifically developed to support effective moisture control in advanced terrarium systems. Designed as a foundational drainage layer, it plays a critical role in bioactive and planted enclosures by preventing waterlogging while supporting biological filtration. This substrate is essential for creating stable, self-sustaining tropical habitats for reptiles and amphibians.

Key Features

• Natural inorganic bedrock designed for superior drainage

• Prevents oversaturation of top-layer decorative substrates

• Non-decomposable material will not rot or break down over time

• Supports the growth of beneficial nitrifying bacteria

• Acts as a biological filtration and percolation system

• Highly porous structure promotes excellent aeration

• Helps prevent anaerobic bacteria and unpleasant odours

• Creates microhabitats for clean-up crews such as isopods and springtails

• Maintains natural moisture gradients for healthy plant root development

• Filtered water can be reused in waterfalls, drip systems, or irrigation

• Ideal base layer for bioactive tropical terrariums and paludariums
