Liquid CO2 Supplement Tetra CO2 Plus, 250 ml, aquarium plant fertilizer

Tetra CO2 Plus is a liquid CO2 supplement for aquarium plants supplied in a 250 ml bottle. Formulated to provide bioavailable carbon to submerged plants, this product supports photosynthesis and can be used where gaseous CO2 systems are not installed or as a complementary treatment. Tetra CO2 Plus is intended for planted aquariums to help maintain healthy leaf growth and overall plant vigor while fitting into routine aquarium maintenance.

Advantages

Tetra CO2 Plus delivers dissolved, plant-available carbon without the need to install pressurised CO2 equipment. The liquid form allows precise dosing and easy integration into regular water change or fertilization schedules. It is suitable for a wide range of aquatic plant species and can help reduce signs of carbon deficiency such as slowed growth or pale leaves when used as directed.

Suitable for

• Planted freshwater aquariums where gaseous CO2 is not used
• Community tanks with moderate light and nutrient regimes
• Temporary carbon supplementation during plant acclimation or recovery
• Complementing gaseous CO2 systems for short-term boosts

How to use

Shake the bottle well before use and follow the dosing instructions on the label according to aquarium volume.

Monitor plant response and overall water parameters while using the supplement, and adjust dosing frequency as needed.

Usage recommendations

Use Tetra CO2 Plus in combination with a balanced liquid fertilizer and regular water changes for optimal plant nutrition. In systems with high light or dense planting, observe plants for signs of imbalance and consider pairing carbon supplementation with appropriate macronutrient and micronutrient dosing. Keep out of reach of children and store in a cool, dry place.
