Seachem Onyx Gravel 15.4 lbs

Product details

Seachem Onyx Gravel 15.4 lbs (3705) is a specially fractured natural aquarium substrate designed to support everyday aquascaping and long-term use in both freshwater and marine setups. Rather than a coated or chemically treated media, Onyx™ gravel is used as the foundation layer of a substrate bed, with a practical emphasis on systems that benefit from carbonate-related buffering—commonly Cichlid aquariums. As a substrate, it can also be combined with other compatible Seachem substrate products such as Onyx Sand™ to create different looks and substrate depths.

Features:

• Made from specially fractured natural substrate for aquarium use
• Suitable for both marine and freshwater environments
• Ideally suited for Cichlid environments
• Rich in carbonates and provides slight buffering capacity
• Not chemically coated or treated
• Works best when used alone as an integral substrate bed, but may be mixed with other gravels/sands such as Onyx Sand™
