Lava Rock Boulders - 5kg

Lava Rock Boulders are relatively smooth shapes boulders ranging in size from 10-20cm (some bigger, some smaller). What we like the most about them though is the shape and the colour.

The clean lines make them ideal for aquascaping and the porous like surface makes gives it a mature look. It's taken years of water passing over them to create this smooth shape and when paired with lush green plants, it looks truly spectacular.

The main picture shows 10kgs of Lava Rock Boulders to give you an idea of sizes and we will do our best to pick a range of sizes but pls consider we can only work with the sizes we have in stock. That said, the more you buy, the better the range tends to be.
