Blue Thumb Ribbed Limestone Sphere Fountain Kit

While the kit includes everything you need for setup, its 320-pound weight means you will need at least two people to safely position the sphere. The plumbing and pump installation are straightforward, but you should have a level, stable surface prepared before assembly.

Limestone is a natural stone that will develop a unique patina over time. To keep it looking its best, gently rinse the sphere with a hose to remove debris and use a soft brush if algae begins to accumulate; avoid harsh chemical cleaners that can damage the stone's surface.

Yes, the included pump features an adjustable flow control valve. You can easily dial the water flow up or down to achieve anything from a subtle trickle to a more pronounced, rhythmic cascade.

We recommend draining the basin and disconnecting the pump during freezing temperatures. If you live in an area with harsh winters, it is best to cover the fountain or move it to a protected area to prevent the limestone from cracking due to ice expansion.

The pump is electric and requires a standard outdoor GFCI-protected outlet. Ensure your installation site is within reach of a power source, or use an outdoor-rated extension cord if necessary.

The frequency depends on your local climate, humidity, and wind exposure, as evaporation is the primary cause of water loss. You should check the water level in the basin weekly and top it off as needed to ensure the pump remains fully submerged.
