By dosing with Flourish Excel you bypass the involvement of chain carbon compounds, and introduce the already finished, structurally similar compounds. - TREATMENT: On initial use or after a major (> 40%) water change, use 1 capful of Flourish Excel (5 mL) for every 40 L (10 US gallons). Thereafter, use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001EUE6SC | | ASIN | B001EUE6SC | | Allergen Information | Gluten Free | | Best Sellers Rank | #98,118 in Pet Supplies ( See Top 100 in Pet Supplies ) #863 in Aquarium Water Treatments | | Brand Name | Seachem | | Customer Reviews | 4.6 4.6 out of 5 stars (2,439) | | Date First Available | June 15, 2004 | | Department | Unisex-Adult | | Global Trade Identification Number | 00000116045605 | | Is Discontinued By Manufacturer | No | | Item Form | Liquid | | Item Type Name | Aquarium Water Treatments | | Item Weight | 8.8 Ounces | | Item model number | 456 | | Liquid Volume | 250 Milliliters | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 456 | | Manufacturer recommended age | 1 month and up | | Model Number | 456 | | Product Dimensions | 4.9 x 2.4 x 2.2 inches; 8.8 ounces | | Target Species | Fish | | UPC | 780231504224 000116045605 | | Unit Count | 1 Count | | Warranty Description | Warranty | ## Product Details - **Brand:** Seachem - **Item Form:** Liquid - **Item Weight:** 8.8 Ounces - **Liquid Volume:** 250 Milliliters - **Number of Packs:** 1 ## Images ![Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 250 ml - Image 1](https://m.media-amazon.com/images/I/510f5gSD3nL.jpg) ![Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 250 ml - Image 2](https://m.media-amazon.com/images/I/61DE3GFxudL.jpg) ![Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 250 ml - Image 3](https://m.media-amazon.com/images/I/618Ad5zC5wL.jpg) ![Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 250 ml - Image 4](https://m.media-amazon.com/images/I/61B0IY2G5-L.jpg) ![Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 250 ml - Image 5](https://m.media-amazon.com/images/I/81XsBrVqySL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 250 ml - Seachem Flourish Freshwater Plant Supplement - Aquarium Element and Nutrient Blend 250 ml - 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.tn/products/4156359-seachem-flourish-excel-bioavailable-carbon-organic-carbon-source-for-aquatic](https://www.desertcart.tn/products/4156359-seachem-flourish-excel-bioavailable-carbon-organic-carbon-source-for-aquatic) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-07*
