i250 mL / 8.5 fl. oz. (Treats 20000 L (5290 US Gallons))
Flourish Iron is a highly concentrated (10,000 mg/L) ferrous iron (Fe+2) gluconate supplement. It should be used in those cases where the iron requirements exceed that which can be delivered by Flourish at the recommended dose. Ferrous iron gluconate is a more suitable iron supplement for aquatic plants than is ferric (Fe+3) iron-EDTA for two reasons. (1)Plants require iron in the ferrous state, so 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. Ferrous iron gluconate is already in the ferrous form so this reduction step is not necessary. (2) Ferrous gluconate is better suited to foliar feeding than is iron-EDTA owing to the relatively weaker iron-gluconate bonding vs. iron-EDTA bonding. Contains no phosphate or nitrate. Guaranteed Analysis: Iron (Fe) 1.0 percent. Derived from: Ferrous Gluconate
DIRECTIONS: Use 1 capful for each 200 L (50 gallons*) as required to maintain about 0.10mg/L iron. For smaller dosing, please note each cap thread is approximately 1 mL. Use MultiTest: Iron test kit to monitor iron concentrations. For 2 & 4 L containers, 1 capful is 10 mL.
Seachem Flourish Iron Supplement 8.5 oz
Seachem Flourish Iron is a highly concentrated iron supplement for aquariums with live plants. Its simple, pure formula is ideal for iron deficiencies and/or situations when iron requirements are greater than what Seachem Flourish can provide.
Flourish Iron contains 10,000 mg/L of ferrous iron (Fe+2) gluconate, a highly effective form of iron that provides greater benefits than ferric state EDTA-iron (Fe+3) sources used in other iron supplements. Plants can only utilize iron in the ferrous state, and must expend extra physiological energy just to make ferric iron supplements usable. Flourish Iron provides plants the iron they need directly, saving time and reducing stress on your plants.
Use Flourish Iron in those cases where iron requirements exceed that which can be delivered by standard Seachem Flourish at the recommended dose, or when signs of iron deficiency appear (including short, slender stems or yellowing between veins).
Directions: Use 1 capful (5 mL) for each 200 L (50 gallons) of water, 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 a test kit to monitor iron concentrations. Use as needed to combat signs of iron deficiency (usually seen in new growth).
