    Hello everyone,

    I have recently been given some rock which I was told is basaltic lava rock. If it passes the vinegar test, and goes through a vigorous cleaning, will it be safe for use in freshwater aquarium?

    I have read that it is inert, but having no first hand experience, I was hoping someone might know?[​IMG]

    Yes, lava rock is safe for tanks
    Do the viniger test anyway for peace of mind but small pieces of lava rock are also often used as filter media

    Just curious. Aren't it always sedimental rocks that can contain chalc not vulcanic based ones ?
