Eheim CO2 Set 400 + Solenoid Valve

Complete CO2 kit for aquariums up to 400 liters with refillable cylinder.
Aquarium water normally contains too little CO2. In addition to light, nitrogen, phosphate, trace elements, etc., CO2 is the most important nutrient for your aquarium plants. The stronger and healthier your plants are, the less chance algae have to develop. Furthermore, plants produce more oxygen than your fish need to breathe, and CO2 also regulates the pH of the water at the right dose.

- Refillable CO2 cylinder (500 g) with cylinder holder
- Precision pressure regulator with gauges and precision dosing valve for refillable systems
