EHEIM CO2 fertilizer systems simply and reliably dose the amount of CO2 needed for healthy plant growth in the aquarium.

Aquarium water almost always contains too little carbon dioxide (CO2). In addition to light, nitrogen, phosphate, trace elements, etc., aquarium plants need CO2 as their most important nutrient. The stronger and healthier the plants grow, the less chance algae have of thriving. They also produce more oxygen, which fish need to breathe. And finally, if dosed correctly, CO2 also regulates the water's pH.
