Our Most Popular Substrate! Please note shipping for substrate costs extra (it's rather heavy!) 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: 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!) 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. Heating Cables: If using undergravel heating cables, ensure the substrate is of medium-fine to coarse grain size to allow proper water circulation. Available Sizes: 5 kg bag 10 kg bag
