First of all, this is very clean. I had clear water even though there was no prior rinsing.It looks very good quality in the tank and it is low tech with root tabs added. Plants are growing nicely ### ⭐⭐⭐⭐⭐ For once, a gimmick that delivers. *by C***. on 12 September 2017* Full disclosure: I have a love/hate relationship with Dennerle. Their products are among the best for price vs longevity, and build quality is to a high standard. However, their replacement parts are overpriced and god help you if you need to contact customer service.But the Germans take their fish-keeping seriously, and this product perfectly exemplifies that.We have a planted aquarium, and needed a black substrate to make the green of the plants really pop and maintain the gorgeous dark color saturation to our L183 Starlight BN and Blue Velvet shrimps. We quickly ran up against what seems to be a wide-spread and persistent problem: finding a black/dark substrate that isn't too sharp for bottom-dwellers (in our case corydoras catfish). We'd tried a number of options, including planting substrates, shrimp substrates, extra fine gravel, and black "sand" -- only to discover that in order to achieve the color without dye, this wasn't technically sand at all, but very finely (and very sharply) ground gravel.Nothing we tried was suitable. Even the largest shrimp substrate, which felt reasonably gentle to the touch, wore down the corys' barbels over time. We were close to admitting defeat and reverting to white sand when we found this product.I'm normally skeptical of gimmicky claims, and the aquarium industry is full of them, but in this case Dennerle have delivered. This gravel is genuinely black, and whatever they've done, appears to be bottom-feeder safe. Two months on and our corys have regrown and maintained their barbels; we also have pygmy corys, variously sized shrimp, otocinclus catfish, and ancistrus using it happily.In my experience, it isn't necessary to rinse this gravel before use; there's no residue to speak of, and barring a couple of grains, it sinks straight to the bottom when poured from the bag.One thing to note if you have a planted tank is that fish waste tends to sit on the top of this product, like sand. This means vacuuming is easier, but fertilizer tabs may become necessary if you notice your plants faltering. Mulm doesn't penetrate the surface as well as with some other substrates. --- ## 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.tw/products/148263328-dennerle-crystal-quartz-gravel-natural-white](https://www.desertcart.tw/products/148263328-dennerle-crystal-quartz-gravel-natural-white) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-22*
