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!

Based on our own experience in customer service and the many messages and questions we receive, we have put together the typical mistakes beginners may make. The experienced aquarist might well smile, but if they are honest, these are mistakes we all made at the start, aren’t they?

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.

Below you will find an outline graphic with examples to explain the structure and interconnections of all the CO2 components.

Have you ever had the chance to see how big the difference really is between a plant aquarium with and without CO2 fertilisation?

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.

A lot of aquarists are talking about liquid CO2, which is said to be able to replace a conventional pressurized gas system or a bio-CO2 system.

Carbon dioxide is the nutritional basis for aquatic plants which is supplemented through micro and macronutrients and light. The balance between all these elements is necessary for thriving plant growth in the aquarium.

The new ProFlora CO2 fertiliser system is the last great innovation we presented at the world's leading trade fair, and it too is even better than its predecessor model. We would like to briefly explain why this is so.

From May 26 to May 29, 2016 the world’s leading trade fair Interzoo opened its doors for the 34th time in Nuremberg. The trade fair, exclusively aimed at the specialist trade, showcased product innovations from all over the world.

Simply put, Liebig’s Law of the Minimum states that the growth of plants is limited by the scarcest resource. Adding a nutrient which already exists in abundance does not influence the growth.

Unlike in natural waters, aquariums with fish mostly have a surplus of nutrients caused by feeding and the resulting fish excrement. Thus nitrates and phosphates in large (often too large!) quantities are available for the plants.

Every evening my aquarium resembles a “whirlpool“ with a thousand little oxygen bubbles. This is the time I relax and wind down after a long day.
