vidaXL Natural Red Volcanic Rocks 3-5 cm 10 kg

These 100% natural volcanic lava rocks bring color and natural filtration to aquatic and landscaping environments. Each piece measures 3-5 cm, contributing to a total weight of 10 kg, and the red-toned, naturally shaped stones create a striking focal point in aquariums. They act as biological filters, helping to improve water quality by boosting oxygen levels and helping to control nitrates, while remaining safe for both freshwater and saltwater setups and not altering the water’s pH. Beyond aquariums, they are suitable for garden landscapes, planter beds, and other landscaping applications, offering versatile decorative and functional use.
