Carbon – the basis of life

Carbon is the most important nutrient for aquarium plants. Around 40 % of a plant‘s dry mass is made up of it. It is usually lacking in aquaria. The consequence: poor plant growth.

The Carbo products supply all aquarium plants with readily available carbon.

All plants, from mosses, to Echinodorus and Cryptocorynes, to fast-growing stem plants, become fuller and stronger. The leaves become considerably larger and the colours more intense. The results are visible within a few weeks – noticeable on the shoot tips and young leaves.

The lush, healthy growth increases the ability of the plants to compete with algae. Unwanted algae are therefore suppressed. The whole aquarium looks healthier and more beautiful.


How does Carbo Booster Max work?


The basis of plant metabolism is photosynthesis. In this biochemical process, energy from the sun is "captured" and stored in energy-rich carbon compounds. One such energy-rich compound is sugar, for example. These compounds are used by plants (a) as universal energy sources or (b) for the production of other compounds. To stay with the example of sugar: Plants can "burn" the sugar in their cells again and use the energy released to drive other metabolic processes. Or they can process the sugar to create cellulose, for example. Cellulose is the substance that gives trees their strength and is made up of nothing more than long sugar chains.

How do plants convert substances into others?
The central hub of plant metabolism is what is known as the citric acid cycle. The citric acid cycle is like a factory. A wide variety of substances are channelled in and the necessary substances are manufactured. Using this metabolic pathway, plants are able to manufacture all the essential carbon compounds themselves: carbohydrates, fats, proteins, vitamins, phytochemicals, etc.

And this is exactly where Carbo products come in. The product contains selected active ingredients that are present in plant metabolism in this or a similar form. The active ingredients are taken up by the plants via the leaves and channelled into the cells. Here they are used as building blocks to create more complex compounds or as an energy source. With this supplementation with carbon compounds, the plants are able to grow more quickly and strongly.

There is also a second effect: All organic substances, that is to say those that are carbon based, are bacterially degradable. The filter bacteria feed on them. In the end all that remains is carbon dioxide (CO2) and water. The active ingredients in Carbo Booster Max are also biodegradable. This means that some CO2 is always formed when using this liquid carbon fertiliser. This CO2 is used by the plants too.

So Carbo products provides the plants with essential carbon via two pathways.

The effect is visible after just a few weeks of regular use: The plants grow faster, are more lush and are healthier. The leaves become bigger and stronger. Tip: Look at the apex and the young leaves. This is where the effect can be seen most quickly. The ability of the plants to compete with algae increases. The whole aquarium appears greener and more magnificent.

  • Application / Dosage

    Depending on the planting and growing conditions:
    1-3 ml per 100 l aquarium water, per day

  • Information about the ingredient glutaraldehyde

    To come straight to the point: With the appropriate dosage and use, Carbo Booster Max is harmless to all fish, plants, shrimps, snails, filter bacteria and other aquarium inhabitants, even with long-term use. Dennerle has carried out practical tests on the product for one year in a variety of aquaria and under different conditions. User safety is a very high priority at Dennerle.

    For the active ingredient glutaraldehyde, the old rule applies: It's the dosage that makes something toxic. In a concentrated form, glutaraldehyde is a hazardous substance – hence the appropriate symbol on the label. At a dosage of 3 ml in 100 l of aquarium water, the active ingredient is diluted to a factor of 33,000. This concentration is enough to considerably promote plant growth, but it is so low that the aquarium inhabitants cannot be negatively affected.

    In the application concentration used here, glutaraldehyde is also very biodegradable. Any that the plants do not take up is "eaten" by the filter bacteria. All that remains is CO2, which again benefits the plants, and water. Even with long-term use, there is no build-up of glutaraldehyde in the aquarium.

    A safety buffer is incorporated into the dosage. Even an accidental double dose has no negative effects. However, you should follow the recommended dosage, proven in practice, and must not use too much Carbo Booster Max.
