Activated Charcoal – 500ml Bag

Create a healthy environment for your terrarium plants with this activated charcoal, an essential component used in many terrarium builds.

Activated charcoal acts as a natural filtration layer within a terrarium. It helps absorb impurities, reduce odours, and keep the enclosed environment balanced so plants can thrive. When placed between the drainage layer and soil, it filters water as it moves through the terrarium system.

How Activated Charcoal Works in a Terrarium

Most terrariums use a layered structure to create a stable ecosystem:

Layer 1: The drainage layer (such as LECA or gravel) collects excess water
Layer 2: Activated charcoal sits above the drainage layer and filters water moving through the terrarium
Layer 3: Terrarium soil sits on top and supports plant growth

This filtration layer helps absorb impurities and maintain a healthier terrarium environment over time.
