Carbo Test Precision Medium CO2 Long-Term Test

Dennerle Carbo Test Precision Medium – A precise CO₂ test for a healthy aquarium

With the Dennerle Carbo Test Precision Medium, you can reliably and continuously monitor the CO₂ levels in your aquarium. An optimal supply of carbon dioxide is crucial for vigorous plant growth, stable water parameters, and the well-being of your fish and invertebrates. This high-quality continuous test allows you to easily and visually monitor the CO₂ level—without the need for complicated measuring devices.

The test uses a precise indicator liquid that changes color depending on the CO₂ level in the water. This allows you to see at a glance whether the level is within the optimal range or needs to be adjusted. Continuous monitoring is essential, especially for planted aquariums with CO₂ fertilization, to prevent deficiencies or overdoses.

Thanks to its high-quality construction and clear color display, the Dennerle Carbo Test Precision Medium is ideal for discerning aquarists who value stable water parameters.

Benefits:

• Precise and continuous CO₂ monitoring in the aquarium
• Simple visual evaluation via color scale
• Supports healthy plant growth
• Increases safety for fish and shrimp
• Ideal for aquariums with a CO₂ fertilization system
• Reliable quality brand from Dennerle
• Suitable for freshwater aquariums

Instructions for use:

1. Fill the designated test chamber with the included indicator solution according to the manufacturer’s instructions.
2. Place the Carbo Test Precision Medium in your aquarium (recommended in the middle to lower section of the tank, where it is clearly visible).
3. Wait a few hours until the indicator liquid has adjusted to the CO₂ level.
4. Compare the color of the test solution with the color chart to determine the CO₂ level.
5. Check the test regularly and adjust the CO₂ supply as needed.

Explanation of test results:

• Blue → CO₂ level too low
  Your plants are not receiving enough carbon dioxide. Increasing the CO₂ supply is recommended.
• Green → CO₂ level optimal
  The value is within the ideal range for healthy plant growth and stable living conditions.
• Yellow → CO₂ level too high
  There is an excess of CO₂. Reduce the CO₂ supply to avoid stress for fish and invertebrates.

Use biocides with caution. Always read the label and product information before use.
