Aquascape's AquaBlox modular water storage system, also known as the D-RainTank by Atlantis, is an efficient way to maximize your water storage capacity in Pondless Waterfall reservoirs.

• Over 3 times more water storage capacity than gravel
• Holds approximately 7.4 gallons of water per cubic foot, as compared to gravel, which holds approximately 2.2 gallons of water per cubic foot
• Extra water storage capacity means less time topping off reservoir due to evaporation
• Easier to clean and less prone to clogging than traditional gravel basins
• The ability to hold more water per cubic foot allows for smaller reservoirs
• Less labor required to excavate and move gravel for basin 
• Uses less liner and geotextile underlayment than reservoirs constructed with gravel
