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.
