Eudrakon N Nitrogen Fertilizer Solution

Ingredients of Eudrakon N

This fertilizer consists of 3 components ensuring a multilayer nitrogen supply:

  • Nitrate
  • Urea resp. Carbamide
  • Ammonium

Ammonium is absorbed instantly and mainly by water plants, but on the other hand, it can not be stored. Due to energetic reasons, it is slightly easier to absorp ammonium than nitrate. But higher nitrate concentrations diminish the ammonium absorption (from approx. 5 mg/l nitrate).
Excess ammonium is quickly oxidized by oxygen consumption into nitrate by nitrifying bacteria. Therefore the fertilizer has a relatively low amount which also helps to avoid toxic ammonia when the pH-value rises above 7.5.

Here, the second content, urea is able to resolve the problem. Urea, a nitrogenous end product of the nitrate metabolism of many animals, can be directly absorbed by plants on the one hand or also hydrolyzed by the bacteria in the tank into ammonium and CO₂.

Nitrates are non-poisonous for animals with all common pH-values and therefore also used as a “storage” here.
Some plants may react with disturbances of growth when a nitrate-rate of 10 mg/l occurs. Therefore, this rate does not need to and should not be exceeded.

A part of the nitrate is added in form of its potassium and magnesium salts, as not only potassium, but also magnesium is consumed in quantity in pools that use a lot of nitrogen.

Dosage

Daily max. 1 ml per 50 l tank water until the requested nitrate concentration is reached.

The optimal concentration is about 3 - 8 mg/l nitrate. Any more is not necessary and only supports the growth of algae.

When no absorption takes place by the plants and there is a complete mineralization, a dosage of 1 ml to 50 l water corresponds to a direct dosage of 2 mg/l nitrate, 0.4 mg/l potassium and 0.1 mg/l magnesium.

Composition

6.8 % nitrate, 2.02 % potassium, 1,0 % urea, 0.48 % magnesium, 0.34 % ammonium, methyl paraben, EDTA

Reiner Stickstoffdünger, funktioniert! Danke Doc ;o)

Zur Nitratdüngung im schwach besetzten Aquarium. Ich filter lieber mit Siporax und dünge bei Bedarf ein wenig nach als dass ich ständig einen hohen Nitratgehalt mit Wasserwechsel bekämpfen muss. Das Leitungswasser hatte hier auch Früher bald 25mg NO3 wodurch das nicht wirklich half.(aktuell so um die 13mg)

Roots conquer the forest

When designing this aquarium, a friend's photo of a large root forming a kind of subway served as inspiration.

Some photos from the aquarium of Wilm Thiere from Braunsdorf

Wilm Thiere has always tried to recreate Amano's aquariums.
