What is Swell Black Lava Gravel Rough?

Swell Black Lava Gravel Rough is a professional quality black lava rock substrate that has been sustainably sourced for a 100% natural look in tropical and coldwater setups alike. As a dark-coloured substrate, with mixed-size gravel, this substrate stands out from artificial gravel and many specialist aggregates. This gravel is even suitable for marine aquariums where a dark bed or floor is needed. 

Why should I choose this black lava gravel?

With a signature lighter coloured granite fleck, this gravel demonstrates that it is the real deal and not artificial gravel that has been coloured black. The unique through-graded range of our kiln-dried Beach 49 rough gravel delivers a natural look that is exceptionally clean. Overall, the smooth rounded particle shape, together with an excess of 96% basalt and granite materials, makes this mixed-size dark grey gravel an ideal product for many aquariums.
