An aquarium waterfall composed of a base, vertical member and cap and wherein a lift tube extends from the base to the cap. A sand reservoir is formed in the base. An air tube operatively connected to the lift tube causes water to rise in the lift tube, and the water carries sand with it from the base to the cap where the mixture of sand and water is redirected in a downward direction toward the base over outcroppings in the vertical member to simulate a waterfall.
