Stacked Slate Spheres Add the charm and beauty of a simple stacked slate sphere fountain to your landscape or garden. The popular globe can be installed as a fountain atop a sub-surface Aquascape AquaBasin® (sold separately), or it can be added to a pond or waterfall for a truly unique landscape element. The lightweight, durable fiber-resin composite construction looks amazingly like real stone but is less expensive. Stacked Slate Spheres are available in five sizes and are ideal for a wide variety of installations and locations. A section of tubing is included for quick and easy installation. Add the exciting element of fire to your fountain urn with the Fire Fountain Add-On Kit for Stacked Slate Fountains (#78221 sold separately).
