TETRA CO2 plus 250ml

Tetra CO2 Plus 250 ml liquid carbon source for planted aquariums

Tetra CO2 Plus 250 ml is an easy to use liquid carbon source for freshwater planted aquariums. Carbon is one of the most important nutrients for aquatic plants, as plants need it for photosynthesis, growth, oxygen production and the development of strong plant mass. Tetra CO2 Plus adds plant available carbon to aquarium water without requiring a pressurized CO2 system.

In planted aquariums, the balance between light, nutrients and carbon is essential. If lighting and fertilization are sufficient but carbon availability is too low, plant growth can slow down and algae may gain an advantage. Tetra CO2 Plus helps support plant vitality and makes plant care easier, especially in small and medium freshwater aquariums.

Use in a planted aquarium

For best results, Tetra CO2 Plus should be combined with suitable lighting, plant fertilization and good water circulation. When plants receive light, nutrients and carbon in balance, they grow stronger and use nutrients more efficiently. This helps make the aquarium more stable and visually greener.

Dosage

Shake the bottle before use. The manufacturer’s basic dosage is 2.5 ml of Tetra CO2 Plus per 20 liters of aquarium water once a week. Use the dosing cap for measuring. In heavily planted aquariums, the product can be used twice a week. Always check the label of the product packaging before dosing.

Before use

Tetra CO2 Plus does not replace complete plant fertilization, but complements plant carbon supply. Aquarium plants also need other nutrients such as nitrogen, phosphorus, potassium, iron and trace elements. Monitor plant growth, leaf color, algae development and fish behavior during use. Avoid overdosing and adjust dosing gradually.

Tetra CO2 Plus 250 ml is a practical choice for planted aquariums where plant growth needs support without separate CO2 equipment. It is easy to dose, suitable for regular weekly use and helps keep plants stronger, greener and better able to compete against algae.
