Tetra Active Substrate, 6 L

To provide aquatic plants with the best conditions for lush growth from the outset, ActiveSubstrate by Tetra is the ideal choice for any aquarium. This natural substrate consists of water-neutral clay minerals which, thanks to their open-pored structure, offer an extensive surface area. This innovative composition ensures 50% higher water permeability compared to conventional gravel, promoting even circulation and ensuring plants are optimally supplied with nutrients.

The clay pores allow even the finest roots to anchor quickly and securely, while the loose structure effectively prevents soil compaction and associated root rot. Furthermore, the substrate supports the colonisation of beneficial soil bacteria, which reduces water pollution and ensures crystal-clear water. With its natural appearance and rounded shape—which protects bottom-dwelling fish from injury—it provides the perfect foundation for a stable and beautiful ecosystem.
