Ferrdrakon Full Iron Fertilizer

Our complete aquarium fertiliser provides aquarium plants with important nutrients and supports vital growth. It is a good idea to buy an iron fertiliser to ensure a basic supply for aquarium plants. Fertilising the aquarium also ensures a particularly intense colouring of the leaves.
All the advantages at a glance:

  • Iron fertiliser as a basic supply for aquarium plants
  • Contains all essential nutrients
  • Supports vital growth
  • Intense leaf colouring
  • Less algae formation

Ferrdrakon complete iron fertiliser as a ready-to-use solution or as a refill pack

Ferrdrakon complete iron fertiliser serves as the basis for fertilising a normally planted tank without any other special features. The complete aquarium fertiliser contains all the important and essential nutrients.

To fertilise aquatic plants, however, supplementary fertiliser products such as Eudrakon N and Eudrakon P can be added to supplement the fertilisation with macronutrients such as nitrate or phosphate if required.

Extremely strong lighting and very dense planting produce strong plant growth. This and trickle filters or UV water clarifiers cause an increased consumption of certain micronutrients. In this case, in addition to the complete aquarium fertiliser, a special fertiliser such as Daydrakon or Ferrdrakon K should also be used.

Iron fertiliser for the aquarium - composition [in mg/L]

Potassium 3,000, iron 1,000, magnesium 750, manganese 400, boron 60, copper 20, molybdenum 20, zinc 20, cobalt 10, nickel 10, iodide 4.6, EDTA, HEEDTA, DTPA, NTA or IDHA*, methylparaben, ascorbic acid

* Please observe the package information.

Weekly addition of Ferrdrakon at recommended dosage [in µg/l]

Potassium 300, iron 100, magnesium 75, manganese 40, boron 6, copper 2, molybdenum 2, zinc 2, nickel 1, cobalt 1, iodide 0.46

Dosage

10 ml per 100 litres of aquarium water every week (± 50 % depending on plant growth)
A daily addition of 1/7 of the amount calculated in this way is advantageous.

When fertilising aquarium plants, start with the lowest possible dosage and only increase slowly. The effect should be monitored: if no further improvement in growth can be observed or problems with algae occur, the dose should be reduced again.
A minimum water change of 25 % every 2 weeks is a prerequisite. More is not harmful, but makes a lot of sense.

Optimum iron content

0.05 - 0.1 mg/litre

Instructions for use

Before use, please follow the instructions before use.

Fertiliser powder weight

13,9 g

Production from 11/21 with IDHA: 14.6 g

Shelf life of the powder mixture

Dark and protected from moisture - shelf life almost unlimited.

The self-prepared solution usually has a light yellow colour. Some time after exposure to air, the colour can deepen to a deep brown or greenish black, but always remains clear. The effect of the fertiliser remains unchanged.

Ferrdrakon Full Iron Fertilizer

Since regular use together with CO2, all plants (various Hygrophilia, Ludwigia, Anubias, Microsorum, Pogostemon helferi, Cryptocoryne) have been growing perfectly. Whether in the substrate (sand) or on stones. I had to clear the Java moss in clumps.
The ivy, which hangs with its roots in the tank, also seems to like it, climbing up the wall unstoppably. Dosing with the dosing pump works very well. Application since May '21.

Since 2002...

Ferrdrakon Full Iron Fertilizer

... I have been using Doc Kremser products.
Ferrdrakon + Terrdrakon are the fertilisers I have been using here for years. I have not yet needed additional fertilisers such as Eudrakon in my "normal" planted/stocked/lit aquarium. Nutridrakon is a new addition. You can get the complete programme here if required;o)

I use the Ferrdrakon here as a daily manual addition (190l/2ml).

Again and again

Ferrdrakon Full Iron Fertilizer

I always like to use the fertiliser. I like to buy the powder for dissolving all products, such as Ferrdrakon K, Daydrakon, Eudrakon P. Eudrakon N is always used as a supplement for my plant tank.

When it started

Ferrdrakon Full Iron Fertilizer

I remember the beginnings of Ferrdrakon. Suddenly plants were growing that otherwise didn't want to. Ferrdrakon is a good and affordable product. I used it for years and was always happy with it. At the moment I still have a lot of leftovers from a third-party manufacturer and when they're used up I'll be happy to switch back. You really can't go wrong with it

Very good complete iron fertiliser

Ferrdrakon Full Iron Fertilizer

A very good complete iron fertiliser! Be patient with the detectability of iron, this will come after a while. I give it an unreserved recommendation to buy. Many thanks also for answering my questions about this.

Great pictures from the plant tank of A.L. from Eckenhaid near Nuremberg

The tank, which is currently almost nine months young, was switched to DRAK almost two months ago. With the fertiliser combination KramerDrak Power and KramerDrak solution as well as good lighting, regular thinning is required.

This is how you can have a good time as a redfin tetra!

The photo was given to me by our customer Peter H. with the comment: “No questions or problems this time, just a photo. :-)”
