Ferrdrakon Full Iron Fertilizer

Ferrdrakon full iron fertilizer as ready-to-use solution or as refill pack

Ferrdrakon serves as a standard full iron fertilizer and delivers the basic supply of iron and trace elements required for every standard pool containing plants, without any further special characteristics. Thus, all important and essential nutrients are contained.
In addition to this fertilizer, supplementary fertilizer products such as Eudrakon N and Eudrakon P can also be used to supplement fertilization with macronutrients such as nitrate and phosphate.

Trickle filter, UV water purifier, extremely strong lighting, very thick planting and consequential very strong plant growth can be the cause of the increased need or consumption of certain micronutrients. In this case the basic nutrient supply should be complimented by using a special fertilizer like Daydrakon or Ferrdrakon K.

Ingredients

3,000 mg/l potassium, 1,000 mg/l iron, 750 mg/l magnesium, 400 mg/l manganese, 60 mg/l boron, 20 mg/l copper, 20 mg/l molybdenum, 20 mg/l zinc, 10 mg/l nickel, 10 mg/l cobalt, 4.6 mg/l iodide, EDTA, HEEDTA, DTPA, NTA or IDHA*, methyl paraben, ascorbic acid

* Please note package information

Weekly addition of Ferrdrakon at recommended dosage

300 µg/l potassium, 100 µg/l iron, 75 µg/l magnesium, 40 µg/l manganese, 6 µg/l boron, 2 µg/l copper, 2 µg/l molybdenum, 2 µg/l zinc, 1 µg/l nickel, 1 µg/l cobalt, 0.46 µg/l iodide

Dosage

10 ml per 100 l tank water each week (± 50 % depending on the plant growth)
Adding 1/7 of this calculated amount each day is beneficial.

It is best to start with an absolute minimum dosage and to slowly increase it. When giving the dosage in this manner, carefully observe the effect it is having: When no improvement in growth is observed and/or problems start with algae growth, you must reduce the dosage immediately.
A pre-requisite for this is that a minimum of 25% of the water is exchanged every 2 weeks. Of course a greater exchange of water does no harm, rather is quite a sensible move.

Ideal iron content

0.05 - 0.1 mg/l

Storage Life

Store in a dark cool place (the metal chelate complexes are sensitive to light) - minimum storage life please see database.

The solution that is delivered normally has a light yellow to dark brown colour. After the entry of air, some time later, it can cause the colour to change to dark brown or eventually green-black, but it always remains clear. The effectiveness of the fertilizer is however not affected in any way by this colour change process.
