Black lava is a unique, natural, dark rock for the aquarium. The characteristic porous structure of the lava with various pore sizes is a beautiful decoration of any aquarium.
Dark lava perfectly contrasts with the green of plants with light roots or ground. The lack of repeatability of the lava additionally gives the reservoir a touch of naturalness and wildness.
After soaking, the rocks darken to reveal they’re true beauty.
Before placing the lava in the tank, it should be thoroughly rinsed under running water. Volcanic rock has no significant effect on the water parameters.
