LIGHT BROWN QUARTZ – Natural Quartz Gravel for Freshwater Aquariums
Tropicalnature’s Light Brown Quartz is a premium-grade natural gravel, ideal for freshwater aquariums. It provides a safe, biologically active and aesthetically natural substrate, ensuring a stable environment for fish and aquatic plants. Colored with iron oxide, this gravel is chemically neutral, non-toxic, and will not alter water hardness, making it safe for all aquarium inhabitants.
With a fine grain size of 1–2 mm, this quartz is ideal for bottom-dwelling fish, thanks to its rounded edges which prevent injuries. Its structure supports strong root development and offers an excellent surface for beneficial nitrifying bacteria, which help maintain biological balance. The gravel is CO₂ and light-resistant, retains its color over time, and can be reused multiple times without degradation.
