These hand selected granite pebbles are inert and fully rounded making them ideal for creating features in Marine aquariums, Tropical and Coldwater setups alike.
The pebbles are dark grey when dry but turn to black when wet.
Unlike other black pebbles on the market these have been sourced prior to the polishing process rendering them completely safe in any aquarium.
These gravels are exceptionally clean having been washed, graded and kiln dried.
