  • Regular price $39.95



Fantastic looking substrate that has no coatings or dyes to wear off or change the water chemistry.

Tahitian Moon is brilliant for tropical or freshwater applications and really shows off fish colours to their best against the shimmering black substrate.

It also enhances the green of plants highlighting their form in the aquarium. This is without a doubt the most popular colour for its striking and universal appeal.



Dramatic black sand rivers and beaches grace the flanks of verdant tropical islands capped by smouldering volcanoes. These exotic locales provide the backdrop for some of the world’s most spectacular aquatic life.

CaribSea’s Super Naturals line is specially selected and crafted to match these exotic environments.
