Activated charcoal is often considered an essential addition to any terrarium setup. 

The incredibly high surface area of these carbon tubes gives it an amazing filtration power that absorbs harmful chemicals and toxins that are taken in by water and from rotting roots and plants.

Please note the charcoal/carbon may arrive either in tube form or in a finer, granular form. Both perform the same function. 


  • Less charcoal is required to be used to cover an appropriate area.
  • Lightweight and therefore protecting your glassware.
  • Promotes aeration.
  • Promotes drainage.

So, What Does What?

Each layer serves a purpose.

Leca, sand and gravel can function as drainage elements and top-level decoration.

Activated charcoal absorbs harmful toxins and chemicals that may find their way into your ecosystem.

And finally, substrates provide nutrition, nutrient delivery, water retention and aeration - to make your ecosystem whole.
