1. Seachem Flourish Iron 500ml Bottles (3 Pack)
Feature
3 Pack of Seachem Flourish Iron - 500ml Each (1500ml Total)No phosphate or nitrate
Highly concentrated
Stops yellowing in veins
Description
Flourish IronTM 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 FlourishTM at the recommended dose or signs of iron deficiency appear (such as short and slender stems or yellowing between veins.) Contains no phosphate or nitrate. Plants are able to much more easily derive a benefit from Flourish IronTM than from EDTA-iron sources because all EDTA iron is in the ferric (Fe+3) state. Since plants require iron in the ferrous (Fe+2) state, additional physiological energy must be expended in order to extract the ferric iron from EDTA-iron and then convert it to the ferrous form.2.

Feature
Organic carbon for planted aquariumsPromotes the ferrous state of iron
Contains no phosphate or nitrate
Description
Flourish excel is a simple source of readily available organic carbon. All plants require a source of carbon. This is typically obtained from co2, but, may also be obtained via relatively simple organic compounds (such as photosynthetic intermediates). Since both processes occur simultaneously one can derive a substantial benefit with the use of flourish excel either alone or in conjunction with co2 injection. Flourish excel also has iron reducing properties which promote the ferrous state of iron (fe+2), which is more easily utilized by plants than ferric iron.5.

Flourish ExcelTM is a source of bioavailable organic carbon.
Description
Flourish ExcelTM is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be derived from simple organic compounds (such as photosynthetic intermediates). The use of either CO2 injection or Flourish ExcelTM does not necessarily negate the use of the other. Because the processes of producing photosynthetic intermediates and building onto them occur simultaneously, one can derive a substantial benefit with the use of Flourish ExcelTM either alone or in conjunction with CO2 . The combination is particularly ideal for situations when continuing to add CO2 could result in dangerously low pH levels. Flourish ExcelTM also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3). The reason plants need CO2 is to produce longer chain carbon compounds also known as photosynthetic intermediates. Photosynthetic intermediates includes compounds such as ribulose 1,5-bisphosphate, and 2-carboxy-3-keto-D-arabinitol 1,5 bisphosphate. Although the names are complicated, the structures are quite simple (5 carbon chains). Flourish ExcelTM does not contain these specific compounds per se, but one that is quite similar. By dosing with Flourish ExcelTM you bypass the involvement of CO2 and introduce the already finished, structurally similar compounds. It is in its structural similarity that Flourish ExcelTM is able to be utilized in the carbon chain building process of photosynthesis. Simple chemical or enzymatic steps can easily convert it to any one to any one of the above named compounds (or a variety of others).6. Pond Flourish Iron, 500 mL / 17 fl. oz.

Easy to dose
Description
FlourishTM is a comprehensive plant supplement for the natural freshwater aquarium. It contains a rich assortment of important micro elements, trace elements and other nutrients. These include calcium, magnesium, iron and other important elements that have been shown to be beneficial to aquatic plants. View a chart of FlourishTM constituents and signs of their deficiency. For macro element (NPK) fertilization, use Flourish NitrogenTM, Flourish PhosphorusTM or Flourish PotassiumTM as needed. Unlike competing products, FlourishTM is designed to be used in conjunction with other macro and micro-nutrient supplements. Other manufacturers try to include ALL necessary nutrients, leading to overdoses of micro-nutrients in an attempt to raise macro-nutrient levels.8. Seachem Flourish Iron, 500 ml

10. Flourish 500ml/17 f. oz. For Freshwater Planted Aquariums!
Feature
Highly concentrated (10,000 mg/L) ferrous iron gluconate supplementPlants are able to much more easily derive a benet 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
Ferrous gluconate has the added bonus of being a source of carbon.
Use 1 capful (5 mL) for each 200 L (50 gallons) or as required to maintain about 0.10 mg/L iron. Use MultiTest Iron test kit to monitor iron concentrations
