AquascapePRO AquaBlox Water Matrix
Best water storage solution for efficient, low-maintenance pondless waterfall installations.
The AquascapePRO AquaBlox Water Matrix is a modular water storage solution designed to maximize capacity within Pondless Waterfall reservoirs. This system, also known as D-Raintank by Atlantis, offers superior performance compared to traditional gravel basins. It achieves approximately 7.4 gallons per cubic foot, significantly outperforming gravel's 2.2 gallons per cubic foot capacity. Utilizing AquaBlox results in a smaller reservoir footprint and reduces the frequency of needing to top off water lost to evaporation. Furthermore, installation is simplified as it requires less labor for excavation and uses less liner and geotextile underlayment than gravel-based systems, while also being easier to clean.

Know before you buy
AquaBlox is significantly more efficient, holding approximately 7.4 gallons per cubic foot compared to just 2.2 gallons for gravel. This allows you to create a much smaller reservoir footprint for the same amount of water storage.
Yes, both the small and large AquaBlox units are engineered for high structural integrity, supporting up to 6,472 pounds per square foot. They are designed to safely sit beneath heavy stone features in a Pondless Waterfall setup.
The system is much easier to maintain than a gravel-filled basin. Because the internal structure is open and modular, it is less susceptible to clogging and debris buildup, making it simpler to keep your water feature clean.
Yes. Because the system maximizes the available water volume in your reservoir, you will need to top off the water less frequently, even during periods of high evaporation.
Actually, the opposite is true. Because the AquaBlox system requires less excavation and creates a more compact reservoir, you will use less liner and geotextile underlayment than you would for a traditional gravel-based basin.
Yes, the AquaBlox system is modular. You can combine the small (9.5" high) and large (17.5" high) units to fit the specific dimensions and depth requirements of your reservoir space.
