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 | | Allergen Information | Gluten Free | | Best Sellers Rank | #98,802 in Pet Supplies ( See Top 100 in Pet Supplies ) #845 in Aquarium Water Treatments | | Brand | Seachem | | Brand Name | Seachem | | Customer Reviews | 4.6 out of 5 stars 2,482 Reviews | | Global Trade Identification Number | 00000116045605 | | Item Form | Liquid | | Item Highlight | Organic Carbon Source for Aquatic Plants | | Item Type Name | Aquarium Water Treatments | | Item Weight | 8.8 ounces | | Liquid Volume | 250 ml | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 456 | | Model Number | 456 | | Number of Items | 1 | | Number of Packs | 1 | | Pet Type | Fish | | 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 ml - **Number of Packs:** 1 ## Images ![- Flourish Excel 250 ml / 8.5 fl. oz. - Image 1](https://m.media-amazon.com/images/I/510f5gSD3nL.jpg) ![- Flourish Excel 250 ml / 8.5 fl. oz. - Image 2](https://m.media-amazon.com/images/I/61DE3GFxudL.jpg) ![- Flourish Excel 250 ml / 8.5 fl. oz. - Image 3](https://m.media-amazon.com/images/I/618Ad5zC5wL.jpg) ![- Flourish Excel 250 ml / 8.5 fl. oz. - Image 4](https://m.media-amazon.com/images/I/61B0IY2G5-L.jpg) ![- Flourish Excel 250 ml / 8.5 fl. oz. - Image 5](https://m.media-amazon.com/images/I/81XsBrVqySL.jpg) ## 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? - 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.it/products/4156359-flourish-excel-250-ml-8-5-fl-oz](https://www.desertcart.it/products/4156359-flourish-excel-250-ml-8-5-fl-oz) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-09-23*
