Fertilising

Don’t let your plants starve!

A lot of aquarium owners have house plants, which they (to some extent) fertilise on a regular basis. Yet they don’t consider a fertilisation for their aquarium plants necessary. In their opinion the aquatic plants receive all the growth requiring substances they need through fish excrement and the water.

But this is only very slightly the case. Yes, the plants are supplied with water and, due to fish excrement, also with nitrogens and phosphates. But no, unfortunately this is not enough!

The main nutrient for plants is carbon dioxide (CO2), which they transform during photosynthesis with the help of light energy and water into food (sugar), releasing oxygen as a by-product.

Somit stellt eine CO2-Düngeanlage die wichtigste Möglichkeit dar, Ihre Aquarienpflanzen mit Nahrung zu versorgen. In Ihrem Aquarium ist zwar durchaus CO2 im Wasser gelöst, aber für die meisten Pflanzen nicht genug, um kräftig zu wachsen.

Wachsen die Pflanzen in Ihrem Aquarium genau so, wie Sie sich das vorstellen?

Wann wachsen Pflanzen optimal? Alle Faktoren für den richtigen Pflanzenwuchs: Licht, LED. Röhren, Düngung, Düngemenge, Düngeüberprüfung, Wechselwirkung mit Wasseraufbereitern, chelatiertes Eisen. Sehen Sie sich einen Versuch zur Überprüfung des Eisens im Dünger an. Ist das enthalten Eisen überhaupt für Ihr Aquarium geeignet? So setzen Sie Pflanzen richtig ein. Wie unterscheidet sich die Düngung von Aquascaping Aquarien gegenüber normalen Aquarien? Wann ist ein NPK Dünger sinnvoll? Wir erklären anschaulich und verständlich, was für ein perfektes Pflanzenwachstum im Aquarium nötig ist.

Welche Faktoren führen zum perfekten Pflanzenwuchs?

Bitte erwarten Sie NICHT, dass der Kauf einer CO2-Düngeanlage alleine zum erwarteten Pflanzenwuchs führt. Es kann klappen, aber auch nicht. Das hat folgende Gründe:

Ihren Aquarienpflanzen benötigen zum Wachsen mehrere Faktoren. Fehlt einer der Faktoren oder liegt als begrenzender Faktor im Minimum vor, wird die Pflanze immer nur bis zur so wachsen, wie es dieser begrenzende Faktor erlaubt. Das einfachste Beispiel wäre Licht: Wenn Sie Ihre Pflanzen mit Dünger, CO2 und Spurenelementen ausreichend versorgen, aber nur 2 Stunden das Licht einschalten, wird die Pflanzen wegen Lichtmangels kaum wachsen. Genau dies trifft auf ALLE Faktoren zu. So kann z. B. Kaliummangel das Wachstum begrenzen.

Comparing this main food CO2 with the food humans need would mean it corresponds to our proteins, fats and carbohydrates. But for us humans these main nutrients alone are not sufficient. Without additional vitamins, minerals and trace elements we could become seriously ill and have a shorter life. In the same way plants require minerals and trace elements as well as CO2, and we can supply these with substrate and liquid fertilisers.

Plant fertilisers

The following fertiliser types are available for your plant care:

Substrate fertilisers

You have two options. Firstly you can put a long-term nutrient substrate ( JBL PROFLORA AquaBasis plus ) as the lowest layer in your aquarium when initially setting it up. With that you provide your plants with all important minerals and trace elements from the start.

After a while the nutrients will be used up and you can replenish the nutrient reservoir in the soil with a liquid fertiliser ( JBL PROFLORA Ferropol ). In addition you have the opportunity to specifically inoculate the substrate during an initial setup with a mixed bacterial culture which prevents the colonisation of unwanted bacteria (Cyanobacteria = blue-green algae) and supplies the plant roots with nutrients bound to the substrate as well as with minerals. With JBL PROSCAPE PLANT START JBL has such a product in its range.

Sollte Ihr Aquarium bereits eingerichtet sein, haben Sie die Möglichkeit Düngekugeln ( JBL PROFLORA 7 Balls ) oder Düngetabletten ( JBL PROFLORA Ferropol Root ) in den Wurzelbereich Ihrer Pflanzen zu stecken. Die Düngetabletten werden alle 30 Tage erneuert und die Düngekugeln halbjährlich.

Liquid fertilisers

Ideally you supply your aquarium plants every week with the basic fertiliser JBL PROFLORA Ferropol . If you combine the fertilisation with the partial water change, AFTER the partial water change you can JBL PROFLORA Ferropol re-dose on basis of the CHANGED water quality. Many popular aquarium plant species, such as Hemianthus, Glossostigma, Elatine and the mosses (Taxiphyllum, Vesicularia, Riccardia, Fissidens, Fontinalis) absorb their nutrients mainly through their leaves. Therefore in this case a liquid fertilisation is more effective than a root fertilisation.

Root fertilisation

With a long-term nutrient substrate ( JBL PROFLORA AquaBasis plus ) you create a perfect basis for a long lasting and healthy plant growth. Through a specific addition of fertiliser balls ( JBL PROFLORA 7 Balls ) your supply for your plants a nutrient depot for about 180 days. But there are also minerals which are consumed very fast. To fertilise them on a monthly basis JBL PROFLORA Ferropol Root has been developed. Please specifically add one fertiliser tablet into the root area of the plants which absorb their nutrients mainly through their roots. These include Echinodorus, Cryptocoryne, Vallisneria, Hygrophila, Bacopa, Alternanthera and Ludwigia etc.

Daily fertiliser

Einige Spurenelemente reagieren im Wasser sehr schnell mit dem enthaltenen Sauerstoff und stehen dann in der oxidierten Form den Pflanzen nicht mehr zur Verfügung. Daher wurde ein Tagesdünger ( JBL PROFLORA Ferropol 24 ) entwickelt, mit dem Sie täglich ZUSÄTZLICH zum Basisdünger die sauerstoffempfindlichen Mineralien und Spurenelemente zugeben können. JBL PROFLORA Ferropol 24 enthält zudem auch die drei Makroelemente Eisen, Magnesium und Kalium. Diese werden zwar mit der wöchentlichen Vorratsdüngung mit JBL PROFLORA Ferropol bereits zugegeben, sollten aber für anspruchsvolle Pflanzenarten in höherer Konzentration zur Verfügung stehen, da deren Wachstum sonst durch einen Mangel an genau diesen drei Mineralien begrenzt wird.

NPK fertilising

Aquariums in which a lot of plants but only few fish live (e.g. aquascapes) often show a lack of nitrogens (N), phosphates (P) and potassium (K). Together with a NPK fertiliser ( JBL PROSCAPE NPK MACROELEMENTS ) you can target dose these substances In such aquariums. Over the ProScape dosage calculator you can determine the actual nutrient consumption in your aquarium and add the nutrients together (NPK fertiliser) or even individually ( JBL PROSCAPE N MACROELEMENTS / JBL PROSCAPE P MACROELEMENTS / JBL PROSCAPE K MACROELEMENTS ).

Aquascapers also like to work with a special highly concentrated basic fertiliser ( JBL PROSCAPE Fe +MICROELEMENTS ). Similar to the JBL PROFLORA Ferropol it contains the most important minerals and trace elements, but also includes the sensitive trace elements which need to be added along with JBL PROFLORA Ferropol and the daily fertiliser JBL PROFLORA Ferropol 24 . Because it is dosed on a daily basis it may contain trace elements sensitive to oxygen.
