## Overview

Aqua Natural Diamond Black is a premium 10lb aquarium substrate made from 100% natural quartz gravel sized 1-2mm. Its ultra-fine grains provide a smooth base that supports aquatic plants and promotes beneficial bacteria growth thanks to its large surface area. The sparkling black quartz creates a stunning contrast in planted tanks, enhancing the visual appeal while maintaining a safe, toxin-free environment for fish and terrariums.

## 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.

Review: Beautiful black sand that sparkles with light - The sand absolutely sparkles in light. It looks great in a fish tank. It’s currently sitting in a 10 gallon tank. When you first pour it in it does get the water a little cloudy but with any good filter it clears up very quickly. I absolutely recommend it for anyone.
Review: Very very fine - almost like sand - beautiful! - I ordered this to add a “sediment” layer for my aquatic plants, and to give a different landscape for my betta Tatsu. I rinsed and soaked them in a bucket overnight to get all the debris out and peace of mind that it’s clean; definitely helped with the cloudiness prior to adding. I added a thin layer across the pea gravel I already have; it was plenty of material for my 10 gallon tank. If used alone with no other substrate/rocks, you’d probably need 2 bags of this for a 10 gal. My pet peeves but doesn’t totally kill the vibe: 1. They don’t sparkle under water at all ☹️ 2. If you have a foam filter like mine that sits at the bottom, these quart rocks are as small as sand and my filter sucked them up and clogged it. I will be getting a top flow filter instead, so not too annoying. 3. I will update once I do a complete tank clean to share how difficult it is to clean with how small they are - by the looks of it, it’ll be a challenge. Wish they were larger size!

### ⭐⭐⭐⭐⭐ Beautiful Sparkly Aquarium Sand
*by L***O on January 1, 2026*

The sand is really pretty. I have a 40 gallon tank with glo fish- I was really wanting to switch from sand instead of gravel because recently I added African dwarf frogs. Since I have glo fish I love the glow-in the dark decorations and vibe- I was pleased that the sand does sparkle under my light. I think I definitely should’ve got three bags instead of just two for my plants. So if you’re second guessing definitely add another one. Overall I am in love with this so far and will be purchasing again. Looks so pretty in the fish tank.
