EHEIM CO2 fertiliser systems offer a simple and reliable method to dose the necessary amount of CO2 for healthy plant growth in the aquarium.

Aquarium water usually contains too little carbon dioxide (CO2). In addition to light, nitrogen, phosphate, trace elements etc., CO2 is the most important nutrient for plants in an aquarium and, when dosed correctly, CO2 can regulate the pH value. The stronger and healthier the plants are, the more oxygen they produce (which the fish need t) and the less chance algae has to grow.

With three complete sets, EHEIM offers the ideal CO2 fertiliser system for aquariums. The “complete set” includes all of the essential equipment and important accessories needed for immediate start up.
