Holey Rock

Holey Rock is a naturally porous limestone known for its unique holes, cavities, and textured surface. Its light, neutral color creates a clean contrast with green aquarium plants, dark substrates, and other aquascaping materials, making it a versatile choice for freshwater aquariums.

Use Holey Rock to create natural-looking rock formations, add height and depth to your aquascape, or build detailed hardscape layouts with plenty of texture. The irregular holes and crevices give each piece a distinctive appearance and can be used to create more complex-looking rock structures.

As a limestone-based aquarium rock, Holey Rock may naturally increase water hardness and pH. Keep this in mind when planning an aquascape for fish, shrimp, or other aquatic livestock that require soft or acidic water. Each piece is naturally unique, so size, shape, color, and the number of holes will vary.

Notes: 

• May affect water chemistry - Test your aquarium water after adding the rock, particularly when keeping species that require soft or acidic water.
• Naturally occurring variations make every piece different
• Porous structure gives the rock its characteristic pitted appearance
• Limestone composition can contribute calcium and carbonate to aquarium water
• May not be ideal for aquariums that require tightly controlled or very low mineral levels
