JBL Sansibar River Substrate is a natural aquarium substrate designed to create a realistic and healthy environment for both freshwater and marine aquariums, as well as terrariums. Its coarse-grained, round-shaped natural sand is gentle on sensitive barbels, making it ideal for digging fish such as rays, kuhli loach, and catfish. 

Key Features:

  • Gentle on Sensitive Barbels: The coarse-grained, round-shaped natural sand prevents injuries to the mucous membrane, ensuring the well-being of bottom-dwelling fish.

  • Suitable for Various Aquatic Life: This substrate is ideal for fish, invertebrates, and plants, as it does not release unwanted pollutants into the water.

  • Supports Plant Growth: When used in conjunction with a nutrient substrate like JBL AquaBasis, it promotes vigorous plant root development.

  • Compatible with Heating Cables: The substrate is well-suited for undergravel heating cables, enhancing water circulation and temperature regulation.

Usage Instructions:

  1. Rinse Before Use: Thoroughly rinse the substrate with tap water to remove any abrasion caused during transit. (you can get away without rinsing if you dont stir the substrate up when filling!)

  2. Layering: Spread the substrate over a nutrient substrate (such as JBL AquaBasis) to promote plant growth. For vigorous root development, a layer of approximately 6-8 cm is recommended.

  3. Heating Cables: If using undergravel heating cables, ensure the substrate is of medium-fine to coarse grain size to allow proper water circulation.
