AquaBlox or Ecoblox are for pondless water features
Small 17 Gallon, 26.5" X 16" X 9.5"
 
Manufactured using recycled materials and designed to efficiently maximize water storage capacity, providing the ability to hold more water with a smaller reservoir footprint. Each Blox will hold approximately 7.4 gallons of water per cubic foot, allowing 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 these Blox will 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.
