## Overview

Aqua Natural Diamond Black is a premium 10lb natural quartz gravel substrate designed for aquariums, fish tanks, and terrariums. Its 1-2mm grain size offers a large surface area that promotes beneficial bacteria growth, reducing buildup and maintaining water quality. The striking black quartz contrasts beautifully with aquatic plants, enhancing the visual appeal of planted tanks. Easy to rinse and safe for all aquatic life stages, this substrate combines natural elegance with functional performance.

## Description

Quartz Gravel is the Rolls-Royce of our range. Natural Quartz not only looks wonderful but has also been shown to help reduce the build up in the aquarium. This is partly due to the huge surface area of quartz which offers added space for the establishment of tank cleaning bacteria. Quartz sparkles underwater due to the many light reflecting facets and is a striking substrate that contrasts well with aquarium plants such as anubias and desertcart swords.
