The Aquascape Large Stacked Slate Sphere makes it easy to add the relaxing sights and sounds of water to any location. The lightweight, durable fiber- resin composite construction is built to last and provides the look and beauty of real rock. Water is pumped up through the center of the fountain and gracefully cascades over the stacked slate texture, creating an impressive effect. The sphere shape is ideal for a wide variety of installations and locations. A section of tubing is also included for quick and easy installation. For ideal water flow rates and storage, we recommend using the Aquascape Ultra 2000 Water Pump or larger and the AquaBasin 45 subsurface reservoir (sold separately). The sphere can also be added to existing ponds for an impressive decorative accent. Add the element of fire to the urn with the Aquascape Fire Fountain Add-On Kit (sold separately) - item 78221.
