Buy Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs at desertcart UK. ## Features - GRAVEL: Seachem Flourite Black 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 freshwater aquarium environment. - AQUARIUM BED: Gravel modifiers such as laterite are not necessary when using Seachem Flourite Black as this product is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. - SET-UP: When adding water to the aquarium, fill slowly to avoid disturbing Flourite Black 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, but to remove this simply use mechanical filtration - COMPATIBLE: Flourite Black substrates will work fine with an under gravel filter and will not soften or decompose to an unsuitable state within your tank.Flourite substrates will work fine with an UGF - SAFETY: Seachem Flourite Black is not chemically coated or treated, thus does not alter the pH of the water. Flourite Black is beneficial for the life of the aquarium and need not be replaced. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0019J0ISU | | Best Sellers Rank | 26,308 in Pet Supplies ( See Top 100 in Pet Supplies ) 57 in Aquarium Gravel | | Brand Name | Seachem | | Country Of Origin | United Kingdom | | Customer Reviews | 4.6 4.6 out of 5 stars (2,654) | | Global Trade Identification Number | 00000116372503 | | Included Components | Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs | | Item Type Name | Aquarium Substrate | | Item Weight | 7 Kilograms | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 3725 | | Model Number | 3725 | | Style Name | Tank Top | | UPC | 000116372503 | | Unit Count | 7000.0 gram | ## Product Details - **Brand:** Seachem - **Global Trade Identification Number:** 00000116372503 - **Item weight:** 7 Kilograms - **Style:** Tank Top - **UPC:** 000116372503 ## Images ![Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs - Image 1](https://m.media-amazon.com/images/I/81MD5ecH5wL.jpg) ![Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs - Image 2](https://m.media-amazon.com/images/I/91rTBK0VpsL.jpg) ![Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs - Image 3](https://m.media-amazon.com/images/I/61L2q0x1-JL.jpg) --- ## 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.vu/products/62288556-seachem-flourite-black-clay-gravel-stable-porous-natural-planted-aquarium](https://www.desertcart.vu/products/62288556-seachem-flourite-black-clay-gravel-stable-porous-natural-planted-aquarium) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-10*
