This means that plants cannot divert iron from older leaves to new ones. Therefore, deficiency symptoms appear first on new or young leaves. Because plants use iron to produce chlorophyll, a lack of iron results in chlorosis, or yellowing, of the younger leaves. Stems may also appear short and slender. If the deficiency is severe and prolonged, each new leaf emerges lighter in color than the preceding leaf. When choosing an iron supplement, it is important to know the distinction between the two forms of iron. The iron will be in one of two oxidation states: ferrous having a +2 charge, or ferric having a +3 charge. Ferrous iron, the preferred iron form and is soluble in water at any pH. Ferric iron, however, is only soluble below a pH of around 5.5; but if the pH is higher than 5.5, which more than likely it will be in a planted aquarium, the ferric iron will become insoluble and precipitate, settling in the root zone. Once this occurs, foliar absorbtion becomes impossible. To overcome this precipitation, competing products employ a chelate of ferric iron: iron-EDTA. While this does keep it soluble, it has a couple of drawbacks with respect to foliar uptake of iron. (1) Iron-EDTA bonding is very strong, thus very little of the iron will be available to the plants over a given time frame and (2) Physiological energy must be expended by the plant in order to extract the ferric iron from EDTA-iron and then convert (reduce) it to the ferrous form. Our approach is different in that we use a complex (not chelate) of ferrous iron in Flourish Ironβ„’. Flourish Ironβ„’ is a highly concentrated (10,000 mg/L) ferrous iron gluconate supplement. Plants are able to much more easily derive a benefit from Flourish Ironβ„’ because ferrous iron gluconate is already in the ferrous form so they do not expend energy reducing it. Despite what other manufacturers may intimate, gluconate is not harmful to plants or fish. In fact, ferrous gluconate is better suited to foliar feeding than is iron-EDTA owing to the relatively weaker iron-gluconate bonding vs. iron-EDTA bonding. In addition, ferrous gluconate has the added bonus of being a source of carbon. ## Features - Highly concentrated (10,000 mg/L) iron source for the planted aquarium - Ferrous gluconate iron - Ferrous gluconate is better suited to foliar feeding than iron-EDTA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002DGL1W | | Allergen Information | Yam Free | | Best Sellers Rank | #129,271 in Pet Supplies ( See Top 100 in Pet Supplies ) #1,183 in Aquarium Water Treatments | | Brand | Seachem | | Brand Name | Seachem | | Customer Reviews | 4.7 out of 5 stars 134 Reviews | | Global Trade Identification Number | 00000116047807 | | Item Form | Liquid | | Item Type Name | Aquarium Conditioner | | Item Weight | 4.71 Pounds | | Liquid Volume | 2 Liters | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 478 | | Model Number | 478 | | Target Species | Aquatic Plants | | UPC | 000116047807 | | Unit Count | 1 Count | ## Product Details - **Brand:** Seachem - **Liquid Volume:** 2 Liters - **Item Weight:** 4.71 Pounds - **Item Form:** Liquid - **Manufacturer:** Seachem Laboratories, Inc. ## Images ![Flourish Iron, 2 L / 67.6 fl. oz. - Image 1](https://m.media-amazon.com/images/I/61ktq3nLrwL.jpg) ![Flourish Iron, 2 L / 67.6 fl. oz. - Image 2](https://m.media-amazon.com/images/I/81DksMRpw-L.jpg) ![Flourish Iron, 2 L / 67.6 fl. oz. - Image 3](https://m.media-amazon.com/images/I/71g-GqI4ScL.jpg) ![Flourish Iron, 2 L / 67.6 fl. oz. - Image 4](https://m.media-amazon.com/images/I/81R466Vi7JL.jpg) ![Flourish Iron, 2 L / 67.6 fl. oz. - Image 5](https://m.media-amazon.com/images/I/91w6wi5yS0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***A on November 12, 2022* ### ⭐⭐⭐⭐⭐ Review *by C***C on March 24, 2014* ### ⭐⭐⭐⭐⭐ Review *by P***D on March 15, 2025* --- ## 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.id/products/15263449-flourish-iron-2-l-67-6-fl-oz](https://www.desertcart.id/products/15263449-flourish-iron-2-l-67-6-fl-oz) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-08*
