VidaXL Volcanic Rocks 3-5 cm 10 kg Red

The volcanic rocks are a natural and versatile addition to your fish tank or aquarium. Made from 100% natural volcanic lava, they are safe for both fresh and saltwater environments and will not affect water pH or chemistry. Their striking red colour and natural shaping provide a colourful, detailed focal feature that enhances the visual appeal of any underwater landscape. Beyond aesthetics, these rocks function as a natural biological filter, helping to improve water quality, boost oxygen levels, and control nitrates to support a cleaner, healthier habitat. They’re also suitable for garden landscapes, planter beds, and other landscaping rock applications, offering flexible usage beyond the aquarium.

Designed for practical versatility, the rocks are light enough to handle easily while presenting a robust, natural appearance. Each piece measures 3–5 cm, and the total weight is 10 kg, making them a substantial decorative and functional addition to your setup.
