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

I have trusted this fertiliser for many years. I have never had such beautiful plants with any other complete fertiliser as with this one. I don't think there is anything better on the market with a sensational price/performance ratio. The dispatch time and order processing are exemplary.

Ferrdrakon Full Iron Fertilizer

Bonjour,

I can only agree with the previous author, that's exactly what happened to me.
It was a complete iron fertiliser from the company "S***" that caused brush algae in my aquarium.
If I hadn't been given the fertiliser for my apple snails, which multiply magnificently in the aquarium, I wouldn't have bought it.

And now my aquarium looks like a bomb has dropped in there because I had to do a lot of "weeding" and the other plants are now also suffering from deficiency symptoms (bleaching etc.) despite the (incidentally quite expensive product).
I can only say one thing: "once Ferrdrakon, always Ferrdrakon".

Salute Reinhard

Ferrdrakon Full Iron Fertilizer

Hello aquarists,do you want good plant growth,fair price-performance... Ferrdrakon!!! I have set up my new aquarium (running for about 3 months), use it mixed with Daydrakon, the Echinodorus plants grow and grow (Green Flame very nice red spots), all other plants are strong, sprout healthy offshoots and in my opinion can not look better.if you want to use it, get ready for the "green infassion" :-) I have used products often enough that I would like to use.... there are products that can do what they are supposed to! Is my honest opinion (P.s. Deliveries, prompt and faster is only possible with "carrier pigeon")

Very good fertiliser at a good price.

Ferrdrakon Full Iron Fertilizer

Very good fertiliser at a good price!
I used to use a no-name fertiliser. After 2 weeks with Ferrdrakon I am amazed at the plant growth. I'm sure there are comparable products from other manufacturers, but I'll stick with Ferrdrakon!
5 stars!

Ferrdrakon Full Iron Fertilizer

Hello everyone,
I use the fertiliser together with Daydrakon in my new aquarium, which I set up 2.5 months ago.
Never before have I had such magnificent plant growth, I was sceptical at first, but now I can highly recommend this product.
In the meantime, my brother-in-law has also switched over and is also delighted.
Conclusion: The best fertiliser I have ever received in 10 years.

Hello to everyone, especially the company owner:
it is an excellent product, the plants grow and grow, you often have to cut them back or give them away, otherwise the fish have no more room in the AQ.

Hello, So far, despite...

Ferrdrakon Full Iron Fertilizer

Hello,

Despite the fertiliser, I have been struggling with algae problems so far. However, it was not due to the Kremser fertiliser (thank Odin). I had too much PO4 (phosphate) in the water. When I removed the rotting root (which was responsible for the PO4 content), the effect was the same as always: "I DON'T KNOW WHERE TO PUT THE PLANTS". Every other fertiliser, whether xxxx YYY or who knows what, can be thrown in the bin. I'm really impressed. Keep it up Andreas.

P.S. Even with algae problems, always work "FOR" the plants, not against them. Of course I'll post pictures after my plants have recovered so that other aquarium enthusiasts can see what great stuff they are. No fake, honest opinion

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. :-)”
