JBL Sansibar Dark Substrate is a premium aquarium substrate designed to enhance the aesthetic appeal and health of both freshwater and marine aquariums, as well as terrariums. Its fine, dark grains provide a sleek, natural look that complements the vibrant colors of aquatic plants and fish.
Key Features:
-
Optimal Grain Size: With a grain size of 0.2–0.6 mm, JBL Sansibar Dark offers excellent support for plant roots, promoting vigorous growth.
-
Prevents Mulm Accumulation: The substrate’s fine granulation and density prevent mulm and other waste materials from seeping in, maintaining a cleaner aquarium environment.
-
Safe for Aquatic Life: Composed of fine granite sand, it is gentle on the sensitive barbels of bottom-dwelling fish and does not release unwanted pollutants into the water.
-
Enhances Natural Colors: The dark substrate reduces light reflections, allowing plants and fish to display their full, natural coloring, which can help easily scared animals feel more comfortable.
Usage Instructions:
-
Rinse Before Use: Thoroughly rinse the substrate with tap water to remove any abrasion caused during transit.
-
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: JBL Sansibar Dark is not particularly suitable for undergravel heating cables due to its fine granulation.
