Aqua Natural Aquarium Substrate in Diamond Black is a premium 10lb bag of fine 1-2mm natural quartz gravel designed to enhance aquatic environments.

## 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.

## Features

- Beneficial Bacteria Support: Promotes good bacteria growth because of its large surface area
- Visual Contrast: Contrasts well with a planted tank to enhance the appearance of your aquarium
- Premium Quartz Composition: Natural quartz gravel sparkles underwater due to light reflecting facets, creating an attractive substrate
- Fine Grain Size: 1-2mm particle size provides optimal coverage and plant anchoring in aquariums, fish tanks and terrariums
- FINE-GRAINED TEXTURE: Graded to 1–2 mm, Diamond Black falls between sand and traditional pebble gravel for a fine, natural-looking substrate.
