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 more gravel for basin
  • Uses less liner and geotextile underlayment than reservoirs constructed with gravel
