Description
Product Overview
Aqua Natural Galaxy Sand is a premium black substrate designed specifically for aquascaping, aquarium, terrarium, and vivarium applications. Each 20 lb (approximately 9 kg) bag contains fine, uniformly graded sand particles that catch and reflect light, creating a dramatic backdrop that highlights plants, rocks, and decorative elements. The sand is ethically and sustainably sourced under license in the United States, ensuring that every grain meets strict environmental standards while providing a consistent, high‑quality product for hobbyists and professionals alike.
The substrate’s dark hue is ideal for creating contrast, making colors pop and providing a natural look reminiscent of riverbeds and forest floors. Its fine texture allows for easy layering and blending with other substrate types, while its stability supports robust plant root systems and encourages beneficial bacterial colonization. The product dimensions of 14 × 10 × 3 inches make it easy to store, transport, and dispense, and the 20 lb weight provides ample material for medium‑to‑large setups without the need for frequent re‑application.

Usage
This black sand excels in a variety of environments. In freshwater aquariums, it serves as a base for planted tanks, enhancing the visual impact of emerald foliage and bright fish coloration. In marine setups, it can be mixed with live sand to create a balanced ecosystem that supports both corals and invertebrates. For terrariums and vivariums, the substrate mimics natural ground cover, providing a comfortable surface for reptiles, amphibians, and insects while retaining humidity and facilitating natural behaviors.
Because the sand is chemically inert, it does not alter water parameters, making it safe for delicate species such as bettas, tetras, and dwarf shrimp. Its fine grain also prevents debris from becoming trapped, simplifying maintenance and water changes. Whether you are setting up a sleek, modern aquascape or a lush, jungle‑style terrarium, Aqua Natural Galaxy Sand offers the versatility and aesthetic appeal needed to bring your vision to life.
