Unlike traditional iron-EDTA products, it provides iron in the ferrous (+2) state, ensuring superior solubility and foliar uptake without taxing plant energy. This results in healthier, greener aquatic plants by preventing iron deficiency symptoms like chlorosis and stunted growth. Trusted by aquascaping enthusiasts for over a decade, Flourish Iron offers a convenient, effective solution to maintain vibrant underwater greenery. ## Description Iron is immobile in plants. 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 Iron™. Flourish Iron™ is a highly concentrated (10,000 mg/L) ferrous iron gluconate supplement. Plants are able to much more easily derive a benefit from Flourish Iron™ 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. Review: good brand - have always used this brand for the past 10 years Review: Great revival of my plants! - I bought this after reading many reviews. This is especially useful for my desertcart sword and deep-red sword plants. They were showing yellow spots on some leaves. After dosing as recommended and cutting off the old leaves, I have not seem new and existing leaves from turning yellow. I bought some red plants (Alternanthera Lilacina, Nesaea Crassicaulis, and Rotala Macrandra) as well, so far they are surviving much better than my experience before. I know there are cheaper options available, such as mixing it yourself with chelated iron powder, but this is definitely much convenient. My brother bought this too, but using the recommended dosage, the water gets cloudy though. ## 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 | |---------------|-------| | Allergen Information | Yam Free | | Brand | Seachem | | Item Form | Liquid | | Item Weight | 4.7 pounds | | Liquid Volume | 2 liters | | Manufacturer | Seachem Laboratories, Inc. | | Pet Type | Fish | | Target Species | Aquatic Plants | | Unit Count | 1 Count | ## Product Details - **Brand:** Seachem - **Item Form:** Liquid - **Item Weight:** 4.71 Pounds - **Liquid Volume:** 2 Liters - **Unit Count:** 1 Count ## Images ![Flourish Iron 2 L / 67.6 fl. oz. - Image 1](https://m.media-amazon.com/images/I/61ktq3nLrwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ good brand *by C***A on November 12, 2022* have always used this brand for the past 10 years ### ⭐⭐⭐⭐⭐ Great revival of my plants! *by C***C on March 24, 2014* I bought this after reading many reviews.

My whole tank turned muddy. Careful how much of this product you use. It does have a lot of iron. If you need a whole lot of iron then this is for you. --- ## 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.in/products/15263449-flourish-iron-2-l-67-6-fl-oz](https://www.desertcart.in/products/15263449-flourish-iron-2-l-67-6-fl-oz) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-30*
