The Tetra Active Substrate is a natural product which provides a suitable medium for aquarium plants to grow in. The large surface and porous nature of the clay granules offers several advantages compared to traditional gravels.

Some of the benefits are:

  • Reduces organic water pollution and helps cycling process
  • Avoids soil compaction
  • Benefits fast rooting of plants
  • Provides plant roots with nutrients
  • Rounded shape of gravel avoids damage to fish
  • Suitable for all freshwater aquariums

A 6L bag is suitable for a 60L tank.

Directions for use: Fill your aquarium with a 4cm high layer of this substrate. For even better plant growth, we recommend a 2-4cm layer of Tetra Complete Substrate.

Tip: Although plants absorb through their roots, it's essential that you offer a liquid nutrient so plants can absorb through their leaves as well (if you're sticking with the Tetra brand then use Tetra Plantamin).
