JBL Sansibar Dark Aquarium Substrate 5kg

JBL Sansibar Dark is a fine-grain aquarium substrate designed for both freshwater and marine setups. With a grain size of 0.2–0.6 mm, it provides a stable base for plant roots while maintaining a clean and natural appearance within the aquarium.

The dense sand structure helps prevent debris from penetrating deeply into the substrate, making maintenance easier and supporting healthier water conditions. Its smooth, rounded granules are gentle on bottom-dwelling fish, making it suitable for species with sensitive barbels.

The dark finish reduces light reflection inside the aquarium, helping fish feel more secure while enhancing the natural colours of both plants and livestock.
