In this video, biologist Heiko Blessin explains why plants need CO2 at all, why aquarium plants have different requirements and how to connect a JBL CO2 system. CO2 fertilisation for aquariums has never been explained more simply or more understandably!

Think back to your childhood. Your bedroom was a small area for you to let your imagination run free. And unsurprisingly you felt like re-decorating and rearranging it at least every three weeks.

Granted, nobody really enjoys testing water. It’s time-consuming and sometimes you’re not sure which colour on the chart your water result matches. But water testing really can be lifesaving – at least for your fish!

This way of directly determining the CO2 content will help you to set the ideal bubble count on your CO2 system and to monitor the quantity you add.

The JBL plant care concept leads to vigorous and healthy growth even with the most demanding aquatic plants. JBL has all the components you need, whether it’s a fertiliser, a bottom substrate or a fully automatic CO2 fertiliser system.

With the right products, aquarium care is not only easy, but can also be a lot of fun! The formulas that make up JBL products are based on intensive research and, especially with care products, their effects are not always immediately visible, yet in the medium and long-term they’ll result in a beautiful aquarium and healthy fish.

Do you have a JBL ProFlora CO2 plant fertiliser system (u series/m series) with disposable or refillable cylinder? Then you can win an exclusive test model.

Professional water analysis sounds very expensive. But the professional water testing in your aquarium or pond at home also works on a high level and above all it is simple and inexpensive.

The discussion, whether aquariums also work without CO2, is as old as modern aquatics itself. One thing is clear: aquatic plants need carbon for their growth.

If we transfer this Liebig’s Law of the Minimum to the aquatic field it quickly becomes clear how important balanced fertilisation is for plant aquariums.

In the fourth part of the series “The story of liquid CO2 fertilisation” we examine what we consider to be the most important aspect. The health of your animals but also of you, the aquarium owners is our number one priority.

In the third part of our series “The story of liquid CO2 fertilisation,” we look at the CO2 content of the “liquid CO2” products which are added to the aquarium.

In the second part of the series “The story of liquid CO2 fertilisation” we examine how glutaraldehyde containing products work on plants.

In the first part of the series “The story of liquid CO2 fertilisation” we look at the active substance of the products considered liquid CO2.

Vaak word in discussies onder aquariumliefhebbers over vloeibaar CO2 gesproken dat een conventioneel CO2-systeem of een bio CO2-systeem zou moeten gaan vervangen.

Kooldioxide is de voedingsbasis voor waterplanten, die aangevuld wordt met micro- en macro-voedingsstoffen en licht. Voor een prachtige plantengroei in het aquarium is een balans tussen alle elementen noodzakelijk.

De wet van het minimum, heel verstandig door Justus von Liebig geformuleerd, komt op het volgende neer: De plantengroei wordt bepaald door de voedingsstof die relatief het minste aanwezig is. Wanneer een voedingsstof wordt toegevoegd, die reeds in ruime mate aanwezig is, dan heeft dit geen enkele invloed op de groei.

In tegenstelling tot natuurlijke wateren is er in een aquarium met vissen doorgaans een voedingsstofoverschot door het voeren en de daaruit voortkomende uitscheiding van de vissen. Zo hebben planten in ruim voldoende mate nitraat en fosfaat tot hun beschikking.

Elke avond ziet mijn aquarium eruit als een whirlpool met duizend kleine zuurstofbelletjes. Dat is het moment dat ik achterover leun en me ontspan na een lange dag.
