Seachem Flourish Iron 500mL
Seachem Flourish Iron is a highly concentrated iron supplement specifically formulated to address iron deficiencies in freshwater aquariums planted with low-light or non-CO2 injected setups.
This targeted formula provides essential iron in a readily available form, promoting healthy plant growth and preventing iron-related deficiencies.
Seachem Flourish Iron is a highly concentrated iron supplement specifically formulated to address iron deficiencies in freshwater aquariums planted with low-light or non-CO2 injected setups. This essential nutrient plays a vital role in plant growth and photosynthesis, and Seachem Flourish Iron provides a readily available source to promote healthy and vibrant aquatic flora.
Features:
- Highly Concentrated Ferrous Iron (Fe+2): Provides a potent dose of iron in the ferrous form, which is more easily absorbed by aquatic plants compared to ferric iron sources.
- Combats Iron Deficiency: Addresses signs of iron deficiency such as stunted growth, yellowing between leaf veins (chlorosis), and transparent leaf tissue.
- Promotes Healthy Plant Growth: Ensures sufficient iron intake for optimal photosynthesis, leading to stronger stems, lusher foliage, and vibrant coloration.
- Safe for Fish and Invertebrates: When used as directed, Seachem Flourish Iron is non-toxic and safe for fish, shrimp, snails, and other aquarium inhabitants.
- Easy-to-Use Liquid: Simply add the recommended dosage to your aquarium water on a regular basis.
Benefits:
- Targets Iron Deficiency: Effectively addresses iron limitations in low-tech planted aquariums.
- Promotes Optimal Photosynthesis: Provides essential iron for efficient energy production in plants, leading to healthier growth.
- Enhances Plant Appearance: Contributes to stronger stems, lush foliage, and vibrant coloration of aquatic plants.
- Safe for Aquarium Ecosystems: Gentle formula ensures the well-being of fish, invertebrates, and beneficial bacteria.
- Easy and Convenient Dosing: Simple liquid format simplifies the process of maintaining adequate iron levels for your plants.
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.
This product uses a complex of ferrous iron in Flourish Iron (not chelate).
Flourish Iron is a highly concentrated (10,000 mg/L) ferrous iron gluconate supplement.
Plants are able to much more easily derive a beneļ¬t from Flourish Iron because ferrous iron gluconate is already in the ferrous form so they do not expend energy reducing it.
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.
Directions:
Use 1 capful (5mL) for each 200 L (50 US gallons) or as required to maintain about 0.10 mg/L iron.
For smaller doses please note that each cap thread is about 1 mL. Use an Iron test kit to monitor iron concentrations.
Due to rapid utilization, test within 30 minutes.
Use as needed to combat signs of iron deficiency (usually seen in new growth) which include: chlorosis (yellowing) of tissue between veins and short and slender stems.
