The Aquascape AquaBlox® Water Storage Module displaces water for use with Pondless Waterfall reservoirs, rainwater collection projects, and other various water feature applications. AquaBlox are manufactured using recycled materials and designed to efficiently maximize water storage capacity, providing the ability to hold more water with a smaller reservoir footprint. Each AquaBlox will hold approximately 7.4 gallons of water per cubic foot, allowing over 3 times the water storage capacity than gravel will provide.
