Aquascape Stacked Slate Sphere Water Features
Modular Slate-Effect Spheres for Custom Fountainscape Builds
 
The Aquascape Stacked Slate Sphere Water Features deliver the visual mass and texture of real stacked stone while remaining practical to install and maintain.
Manufactured from a durable fibre-resin composite, they are significantly lighter than natural rock, making them far more installer-friendly on site.
Designed specifically for use within the Aquascape Fountainscape system, these spheres give you full control over pump choice, reservoir size, and overall layout.
 
Why Choose the Slate Sphere
Authentic stacked stone appearance without the weight
Tool-free assembly – faster, safer installations
Engineered water flow for even spill on all sides
Modular system – scale from small gardens to commercial features
Ideal where a strong focal point is required without constructing a pond.
Intelligent Basin & Flow Control
 
Each sphere features a built-in top basin that fills before water spills evenly over the surface:
Four internal baffles reduce water velocity
Ensures smooth, symmetrical overflow
Prevents aggressive splash and pump strain
 
Only the small internal basin needs to fill for circulation, not the entire sphere. This:
Reduces reservoir size requirements
Lowers back pressure on the pump
Improves efficiency and long-term reliability
 
Tool-Free Modular Assembly
Supplied in four interlocking sections
Slot together easily with no tools required
Simplifies handling and installation in restricted access areas
For added stability, weight can be placed inside the lowest section (e.g. bagged gravel or stones).
 
Supplied Plumbing
Each Stacked Slate Sphere includes:
Clear 19 mm flexible tubing
Integrated disc fitting that locks into the basin inlet
Connects directly to your chosen pipework or pump setup
Clean, reliable, and fully compatible with Aquascape plumbing systems.
