    Scientists at Columbia University have discovered that a rock found in the Middle East can be used to soak up carbon dioxide at a rate high enough to significantly slow global warming.

    The team found that when the rock, known as Peridotite, comes into contact with carbon dioxide it converts the gas into harmless minerals such as calcite.

    Peridotite is found in the Earth's Mantle layer which is ~2,890 km thick (1,800 miles) rocky shell comprising approximately 70% of Earth's volume

    This rock would be great for our reef tanks :cheesy:

    very interesting but for a reef tank. maybe not. other minerals in the rock can leach into the tank, couldn't it? like copper etc...

    i dunno im no scientist
