Aqua Nova Basalt Gravel 5–10 mm 5kg Bucket – Natural Aquarium Substrate

Aqua Nova Basalt Gravel is a premium natural aquarium substrate with a larger 5–10 mm grain size, ideal for creating bold, natural aquascapes and aquariums with larger fish. Its dark basalt colour enhances the natural colours of fish, plants, rocks, and driftwood, creating a striking and realistic underwater environment.

Made from natural basalt, the gravel is chemically inert and does not affect pH, GH, or KH, making it suitable for a wide range of freshwater aquariums. The larger stones provide excellent water circulation through the substrate and are particularly suitable for larger aquariums, cichlid tanks, and decorative layouts.

Supplied in a durable 5 kg bucket, the substrate is easy to transport, store, and use during aquarium setup or maintenance.
