Fluval Bio Stratum is a premium substrate made from 100% natural volcanic soil sourced from Mount Aso, Japan. Its unique mineral-rich composition, combined with beneficial nitrifying bacteria, jumpstarts biological activity to create the perfect environment for your planted aquarium. The lightweight, non-compacting 1 mm granules allow fine roots to spread easily, absorbing essential nutrients and trace elements that fuel vigorous plant growth and enhance overall health. Choose Fluval Bio Stratum to ensure your aquatic plants thrive with lush, vibrant growth from the very start.

  • Promotes healthy plant development, vigorous growth and vibrant color
  • Infused with dormant beneficial nitrifying bacteria that, once in contact with water, are activated to break down waste and kickstart the nitrogen cycle
  • Rapidly reduces ammonia levels to help stabilize water conditions in new aquariums
  • Lightweight 1 mm granules are non-compacting and allow even the finest and most delicate roots to easily penetrate and spread throughout substrate
  • Porous granules promote extensive bacterial colonization and act as an additional source of biological filtration for improved water quality
  • Includes a powerful mix of plant-friendly nutrients, minerals and trace elements
  • Helps support a neutral to slightly acidic pH – ideal for live plants as well as tropical fish and shrimp commonly kept in planted aquariums
  • Softens water naturally, reducing carbonate hardness
  • Will not stain water and helps control organic discoloration
  • Unique curing and heat treatment process helps extend soil life and ensures no parasites are present
