Its 1-2mm grain size anchors plants effectively while its large surface area promotes beneficial bacteria growth, ensuring a cleaner, healthier tank. The sparkling facets create stunning visual contrast, making it the perfect substrate for professional aquarists seeking both function and style. ## 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 coarse sand - This is not fine sand nor is it small gravel. It's large sand. It is pretty easy to work with unlike sand and is easy on the bottom dwellers unlike gravel. Naturally colored it will bleed out a little while preparing. I did several rinses and soaks over 2 days before putting in the tank. It sparkles under the light but with no glare. vacuums pretty easily, you will get some up the tube but just let it sink to the bottom of the bucket, pour out and pinch it back into the tank. Simples. Would re-order again. This is the only thing IMO that competes with Carib Sea Supernaturals Peace River which is the perfect substrate in all situations. Just hard to fine and boring in color. Review: Great product, just don't expect "black" black - My favorite brand of substrate, comes pre washed so I don't have to worry about that. Just know that it isn't solid black. It looks black in the bag but once you get it I'm your tank and add water it's more like a speckled look, I'll see if I can find a photo. But good none the less. I might try some of the other colors since I know I won't get that black color I was looking for. But I'll still use the same brand ## Features - Aquarium Safe Material: 100% natural composition ensures safety for all aquatic life - 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 ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 2,517 Reviews | ## Images ![Aqua Natural Aquarium Substrate, Diamond Black Fine Gravel, 10lb - Image 1](https://m.media-amazon.com/images/I/714Ra42cUIL.jpg) ![Aqua Natural Aquarium Substrate, Diamond Black Fine Gravel, 10lb - Image 2](https://m.media-amazon.com/images/I/71YW9Ajw33L.jpg) ![Aqua Natural Aquarium Substrate, Diamond Black Fine Gravel, 10lb - Image 3](https://m.media-amazon.com/images/I/71GnrdhokHL.jpg) ![Aqua Natural Aquarium Substrate, Diamond Black Fine Gravel, 10lb - Image 4](https://m.media-amazon.com/images/I/A1-0NnrGDwL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Beautiful coarse sand *by J***G on October 3, 2023* This is not fine sand nor is it small gravel.

Just know that it isn't solid black. It looks black in the bag but once you get it I'm your tank and add water it's more like a speckled look, I'll see if I can find a photo. But good none the less.

But I'll still use the same brand ### ⭐⭐⭐⭐⭐ A Nice Fine Gravel. *by R***B on June 30, 2026* Looks exactly as it should. It needed a good rinsing but that was expected. Black enough for me. Don't care about sparkles. Some reds and browns give it some contrast. This works for me. ## Frequently Bought Together - Aqua Natural Diamond Black 10lb, Premium Gravel and Substrate for Aquariums, Fish Tanks and terrariums, 1-2mm - Aqua Natural Sugar White Sand 10lb Substrate for aquascaping, Aquariums, vivariums and terrariums - majoywoo Natural Coral Driftwood for Aquarium Decor Fish Tank Decorations, Assorted Driftwood Branch 6-10" 3 Pcs, Reptile Decor… --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/270779964-aqua-natural-aquarium-substrate-diamond-black-fine-gravel-10lb](https://www.desertcart.us/products/270779964-aqua-natural-aquarium-substrate-diamond-black-fine-gravel-10lb) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-06*
