CO2 good for plants but not body

Finally invested in a CO2 system for my aquarium plants.  Plants continued to die with adequate light.  Need to experiment with the number of CO2 bubbles per minute for optimal plant growth.  

However, too much CO2 in a human body causes carbon dioxide narcosis and death.  Occurs in patients with severe COPD.
