Black Lava Rocks for Fire Pit - 20 lbs

Our Natural Lava Pebbles are sourced from volcanic areas in East Asia and tumbled into round, consistent pebbles through a natural solidification process. These all-natural lava rocks offer a variety of practical and decorative applications, from fire pits and landscaping to aquariums and terrariums.

When used in gas fire pits, our lava pebbles excel at evenly distributing heat, requiring less gas consumption to maintain warmth. They continue providing heat even after the flame is extinguished, offering greater efficiency and cost savings compared to artificial fire logs.

In landscaping and water features, our lava pebbles create an eco-friendly environment for plants, trees, and aquatic life. They serve as an excellent drainage layer, soil cover, and moisture retention solution. The porous nature of the pebbles also helps aerate the soil and prevent erosion.

For aquarium use, our lava pebbles act as a natural filter media without affecting the water's pH levels, making them safe for fish and plants. Before placement, it is recommended to rinse the pebbles thoroughly to remove any dust or powder residue that could cloud the water.

Lava pebbles also excel in terrariums, as their porous structure allows them to absorb and retain heat exceptionally well, creating an ideal microclimate for the enclosed ecosystem.

Our natural lava pebbles come in a variety of sizes, ranging from 0.5 to 5 inches in diameter, and in shades of black, dark gray, and light gray. The round, tumbled shape and natural, unpolished finish give them a consistent and visually appealing look.

When selecting the appropriate size, it's recommended to compare the pebbles to a quarter dollar to get a better idea of the scale. For fire pit applications, the coverage can be calculated based on the pit's dimensions, with approximately 1 pound of pebbles per 20 cubic inches of space for rectangular pits and 1 pound per 25 cubic inches for circular pits.

With a 4.4-out-of-5-star customer rating, our natural lava pebbles have proven to be a versatile and reliable choice for a wide range of indoor and outdoor uses. Whether you're looking to enhance your fire pit, create a stunning landscape, or set up a thriving aquarium or terrarium, our lava pebbles offer a natural and functional solution.
