AquaBlox Water Storage Module Small - Maximizes Pondless Reservoir

In this review the Aquascape AquaBlox Small water storage module is evaluated for homeowners and landscapers who need more reliable water storage for pondless waterfalls, rain gardens, or drainage projects. The bottom line: the AquaBlox Small packs a lot of water capacity into a compact footprint, making it an effective choice for reducing how often a reservoir needs topping off and for increasing infiltration volume compared with traditional gravel basins. It is a straightforward solution for anyone wanting improved water retention without a large excavation.

Key Features

• High storage density: The Small module holds 17 gallons in a 26.5 x 16 x 9.5 in footprint, allowing more water in a smaller reservoir than loose gravel.
• Reduced maintenance: The molded block is easier to clean and less prone to clogging than a gravel basin, which helps keep drainage and infiltration working reliably.
• Evaporation reduction: More stored water means less frequent topping off from evaporation for pondless waterfall systems and features.
• Recycled construction: Manufactured from recycled materials, the block provides a durable storage option with an environmental advantage over some alternatives.
• Multipurpose use: Suitable for Pondless Waterfall reservoirs, RainXchange projects, and other water feature or garden drainage applications for flexible site use.

Who It's For

The AquaBlox Small is best for homeowners, landscape contractors, and gardeners who need to maximize underground water storage in limited space and prefer a low-maintenance alternative to gravel. It fits projects that require a compact module to increase reservoir capacity without enlarging the excavation footprint and for users who value easy cleaning and clog resistance.

Those who should look elsewhere include projects requiring extremely large single-volume tanks or systems needing custom-shaped storage; in those cases multiple sizes or different containment options may be more appropriate. Also, if your design depends on decorative visible elements rather than buried storage, this is a functional rather than aesthetic component.

Pros & Cons

Pros

• Significantly more water storage per cubic foot than gravel, helping reduce refill frequency.
• Sturdy, easy-to-handle modules that customers report as simple to assemble and place.
• Less prone to clogging and easier to clean than traditional gravel basins, which helps long-term performance.
• Made from recycled materials, offering a more sustainable option for water storage.

Cons

• As a buried module it is a functional solution only, so it is not suitable where visible or decorative tanks are required.
• One module provides a modest 17 gallon volume, so larger systems require multiple modules or the larger size option.
