Product Description
Carbon – the basis of life.. Carbon (carbon dioxide) is the most important nutrient for aquarium plants. Around 40% of the plant's dry matter consists of it, which is in short supply in the aquarium. The result: poor plant growth. And if the plants grow poorly, the unloved algae get their chance. Carbo Care Pro provides all aquarium plants with readily available carbon quickly and effectively. All plants, from mosses to echinodores and cryptocorynes to fast-growing stem plants, become fuller and stronger. The leaves become much larger and more colourful. The success is visible after just a few weeks - pay attention to the shoot tips and the young leaves. The lush, healthy growth increases the competitiveness of the plants against algae. Undesirable algae are thus pushed back. The entire aquarium appears healthier, greener and more beautiful.. How Carbo Care Pro works. The basis of plant metabolism is photosynthesis. In this biochemical process, solar energy is "captured" and stored in energy-rich carbon compounds. One such energy-rich compound is sugar, for example. These compounds are used by the plant (a) as a universal source of energy or (b) used for the production of other compounds. To stay with the sugar example: The plant can "burn" the sugar in its cells again and drive other metabolic processes with the energy released. Or it can process the sugar into cellulose, for example. Cellulose, also known as wood pulp, is the fabric that gives trees their strength and consists of nothing more than long chains of sugar. How can the plant convert substances into each other? The central hub in plant metabolism is the so-called citric acid cycle. The citric acid cycle is like a factory. A wide variety of substances are introduced here to produce the required substances. With the help of this metabolic pathway, the plant can produce all vital carbon compounds itself: carbohydrates, fats, proteins, vitamins, secondary plant substances, etc. And this is exactly where the Carbo Care Pro comes into play. The product contains selected active ingredients that also occur in plant metabolism in this or similar form. The active ingredients are absorbed by the plant and used in the cells as a building material to build higher compounds or used as an energy source. This additional supply allows the plant to grow faster and stronger. In addition, there is another positive effect: All organic active ingredients based on carbon are bacterially degradable, because the numerous filter bacteria in the aquarium feed on them. In the end, only carbon dioxide (CO2) and water left. Carbo Care Pro thus supplies the plants with vital carbon in 2 ways. The effect is visible after just a few weeks of regular use: the plants grow faster, more abundantly and healthier, algae are pushed back.. Application/Dosage. Depending on planting and growing conditions: 2 – 4 ml daily to 100 L of aquarium water. Information about the ingredient Glutaraldehyde. Carbo Care Pro is harmless to all fish, plants, shrimps, snails, filter bacteria and other aquarium inhabitants when dosed and used correctly, even with long-term use. The product had to undergo an endurance practical test in various aquariums and under different conditions. User safety is a very high priority at Dennerle. The old rule also applies to the active ingredient glutaraldehyde: the dose makes the poison. Glutaraldehyde in concentrated form is a hazardous substance. At a dosage of 3 ml per 100 L of aquarium water, the active ingredient is diluted by a factor of 33,000. This application concentration is sufficient to significantly promote plant growth, but is so low that the aquarium inhabitants cannot be negatively influenced. In addition, glutaraldehyde is highly biodegradable in the application concentration used here. What the plants do not absorb is "eaten" by the filter bacteria – only CO remains2, which in turn benefits the plants, and water. Even with long-term use, there is no accumulation of glutaraldehyde in the aquarium. A safety buffer is built into the dosing. Even an accidental double dosage does not lead to negative effects. In principle, however, you should follow the recommended and tried and tested dosage and not overdose on Carbo Care Pro.
