AquaBlox are ideal for use with Pondless Waterfall reservoirs, RainXchange projects, and other various water feature applications. AquaBlox are manufactured using recycled materials and designed to efficiently maximize your water storage capacity, providing the ability to hold more water with a smaller reservoir footprint. Each Small AquaBlox will hold a total volume of 17 gallons. Holding approximately 7.4 gallons of water per cubic foot, the Small AquaBlox allows over 3 times the water storage capacity than gravel will provide. This extra storage capacity will mean less time needed to top off the reservoir due to evaporation. Using AquaBlox will also decrease the amount of labor, liner, and underlayment required during installation. The load-bearing top will support up to 5,472 pounds per square foot, providing years of trouble-free enjoyment and allowing for installation in a wide variety of situations. Aquascape AquaBlox are easier to clean, less prone to clogging, and come complete with the top, bottom, two sides and four structural supports. Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
