AquaGlow Black Aquarium Sand Substrate (10 lb)

Fine-grain black sand substrate (0.5–1.5mm) that creates a dramatic dark backdrop, making fish colors appear more vivid. Ideal for corydoras, kuhli loaches, and other species that sift through soft substrates without injury. The rounded particle shape prevents impaction in sand-sifting fish. Pre-rinsed to reduce initial cloudiness — rinse thoroughly before use for best clarity.
