It supports robust plant root growth without altering water pH, offering a rich dark base that enhances aquarium aesthetics. Pre-washed and chemical-free, it requires minimal preparation and works well alone or mixed with other gravels, making it a top choice for professional aquascaping enthusiasts. ## Description Flourite dark is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any aquarium environment. Flourite dark is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as Laterite are not necessary. Flourite dark is not chemically coated or treated and will not alter the pH of the water. Although it is pre-washed, because Flourite® Dark is a natural product, it will become dusty in transit and require thorough rinsing before use to remove any residual dust ( rinse until water runs clear through substrate). When adding water to aquarium, fill slowly to avoid disturbing Flourite® Dark substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal. To remove cloudiness, use mechanical filtration (such as filter floss). Use Clarity™ to accelerate clearing. ## Features - Aquatic - Additives & Supplements - Plant Care - Flourite Dark Clay Based Plant Gravel 7 Kilo ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001NTFXHW | | ASIN | B001NTFXHW | | Allergen Information | Gluten Free | | Best Sellers Rank | #76,798 in Pet Supplies ( See Top 100 in Pet Supplies ) #337 in Aquarium Décor Plastic Plants | | Brand Name | Seachem | | Customer Reviews | 4.4 4.4 out of 5 stars (1,966) | | Date First Available | June 8, 2005 | | Global Trade Identification Number | 00000116373500 | | Is Discontinued By Manufacturer | No | | Item Form | Granules | | Item Type Name | Aquarium Substrate | | Item Weight | 7 Kilograms | | Item model number | 3735 | | Liquid Volume | 15.4 Liters | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 3735 | | Model Number | 3735 | | Pet Type | Fish | | Product Dimensions | 17 x 11.75 x 1.75 inches; 15.43 Pounds | | Target Species | Fish | | UPC | 000116373500 | | Unit Count | 1 Count | ## Product Details - **Brand:** Seachem - **Item Form:** Granules - **Item Weight:** 7 Kilograms - **Liquid Volume:** 15.4 Liters - **Unit Count:** 1 Count ## Images ![Flourite Dark, 7 kg / 15.4 lbs - Image 1](https://m.media-amazon.com/images/I/81DMVHNk3LL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How does it taste?** A: I haven't tasted it myself but my plants seem to really like it. **Q: How do you clean this stuff on a regular basis? I read some where not to use the handheld tube vacuum. ??** A: Tube vacuum should work fine. I’d imagine whom ever wrote that hadn’t rinsed it very well and kicked up a ton of sediment. It’s really just chips of clay, nothing that should interfere with a vac any more than a gravel would! **Q: Will my plants live with only this substrate?** A: I have only this substrate in my 29 gallon and it is sufficient to grow plants. I recommend periodically supplementing with Flourish in order to maximize plant growth, but a decent group of fish will provide enough nutrients for decent plant growth. **Q: the description for this item reads 7k / 15.4 lbs but the item pictured reads half that 3.5k / 7.7 lbs; which is correct for the item?** A: The container I received had 15.4 lbs., someone made an error. ## Frequently Bought Together - Flourite Dark, 7 kg / 15.4 lbs - Fluval 12695 Plant and Shrimp Stratum for Freshwater Fish Tanks, 17.6 lbs. – Aquarium Substrate for Strong Plant Growth, Supports Neutral to Slightly Acidic pH - Seachem Flourish Tabs Growth Supplement - Aquatic Plant Stimulant 40 ct --- ## 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.be/products/7411595-flourite-dark-7-kg-15-4-lbs](https://www.desertcart.be/products/7411595-flourite-dark-7-kg-15-4-lbs) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-14*
