Lava Aquarium Rock – Large

The Lava Aquarium Rock is a decorative stone for building aquarium hardscapes. Porous lava rock is lightweight and offers lots of surface area for beneficial bacteria and for attaching plants. Combine several pieces to create natural-looking ridges, caves and focal points in planted and community tanks. This listing is the Large option.

Building with lava rock

Three sizes are offered: Small, Medium and Large. Because lava is light for its size, larger pieces can be stacked into tall structures without putting as much weight on the glass as dense stone. Its rough, porous surface is ideal for attaching mosses, Anubias, Bucephalandra and ferns: tie them on with cotton thread or fix them with aquarium-safe glue, and the roots will grip within a few weeks. The edges can be sharp, so check placement around fish with long fins or delicate skin.

Good to know

Rinse each piece before use, plan the layout on the empty tank floor first, and check water hardness after adding new stone, as some rocks can raise it slightly.
