WIO Nano Rocks - Paleorock

WIO Paleorock Nano Stone brings geological wonder, fossil history, and natural alkalinity to nano scale — a lightweight and porous sedimentary stone featuring fossil shapes, tunnels, and marks that add a sense of ancient wonder to any habitat, perfectly sized for nano aquariums, marine tanks, and cichlid setups.

Paleorock Nano Stone carries the same unique fossil-marked character as the full-size Paleorock — a lightweight and porous stone whose surface is etched with fossil shapes, tunnels, and marks that are a testament to the ancient living creatures that once inhabited the earth. Its high mineral content and alkalinity make it ideal for fish that prefer alkaline waters, and its porous surface provides perfect texture for beneficial bacteria to grow and thrive.

Sized between 3 and 10 cm, ideal for nano tanks under 40L, nano marine tanks, and small African cichlid setups. May raise pH and hardness; regular water changes keep hardness under control. Pre-washed and ready to use.
