Fill sieve with some gravel, and run under water (using your hand to spray the water for even coverage). Do it for about 15 sec. Decant gravel into bag, or another bucket. PUT KETTLE ON, TAKE A BREAK, WRITE A REVIEW> repeat.2. gravel will be the above image colour in the tank. I added a white sheet for reference for everybody different screen colour. Its not the midnight black that you think it might be. Light on aquarium is daylight balanced for plants.Overall, I suspected it might need rinsing and cleaning. The gravel itself is not round, rather angular. So consideration is needed if you have fish or invertebrate that crawl around on it. Its not razor sharp, but its not smooth either.ABOVE IS IMAGE FOR SHAPE AND A ADDED PENCIL TIP FOR SIZE REFERENCE, on a white sheet.NOTE>>>it looks BLACKER outside of aquarium!I gave it 4 stars, as it is what I required. ### ⭐⭐⭐⭐⭐ Looks great, just make sure you properly wash it! *by M***K on Reviewed in the United Kingdom on 7 May 2020* Ordered this as I needed an inert substrate where I wouldn't have to worry about the parameters as much. This was reasonably priced and just what I needed for my plants as well.First time setting up a sand tank so I followed the advise to wash the sand. Ordered 20kg for my 125l tank which has given me a 4-5cm layer throughout. I read somewhere on here that it was recommended to wash this only once.... DEFINITELY NOT. I had to wash this sand alot! Rinsed each 10kg bag in a large bucket, filling it with water, stirring and then draining.... 10 times. Even after the 10th rinse it wasnt clear but was alot better than if I only washed it once.In the tank it looks amazing, it seems to hold down plants alot better than fluval stratum which i have also used previously. There are no fertilisers/nutrients in this but those can be added. Free clay balls were also provided so that was nice.The water is still a little cloudy but hopefully this clears in a few days. The fish seem to like it, don't have any bottom dwellers but my rainbow shark looks alot happier.Can't fault it so far, as expected. Hope it is really good for the plants I will be adding in the next few days. ### ⭐⭐⭐⭐⭐ Over the moon 😁 *by A***A on Reviewed in the United Kingdom on 25 March 2021* OMG! So much easier to clean rather than our old black gravel. It's quite fine, but not too fine for cichlids and they really enjoy it. In direct sunlight it looks grey, but during the night time, when the aquarium lights are on its white. I'm suuper excited about it! Value for the money? Definitely. Satisfied? Over the moon. 😁 It's practicaly the 3rd time ordering, but the 2nd time doesn't really count as the package did not arrive. They were really cooperative and we got a refund imediately.All in all, keep it up! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/93996160-aquarium-gravel-natural-fish-tank-substrate-for-plant-growth-5kg](https://www.desertcart.tn/products/93996160-aquarium-gravel-natural-fish-tank-substrate-for-plant-growth-5kg) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-24*
