Automatic digital pH control for CO2 operations Processes such as the addition of CO2 to water are reliant on the pH levels, which can be effortlessly monitored and adjusted through the pH value. The seramic pH Controller keeps an eye on the pH levels of your aquarium water and manages a connected CO2 fertilization system based on the set parameters. This is achieved by linking the device to the seramic pH Controller via a socket, allowing you to define the desired pH ranges, which are then autonomously and accurately maintained by the seramic pH Controller. The included solenoid valve can easily connect to standard CO2 systems and manages the addition of CO2 in relation to the pH levels. The kit includes: digital seramic pH Controller with power connection and external plug solenoid valve sera pH electrode 2 suction cups and a universal holder universal holder plate sera test solution pH 4.0 (with safety color indicator “red”) 100 ml (3.38 fl.oz.) sera test solution pH 7.0 (with safety color indicator “green”) 100 ml (3.38 fl.oz.) 3 m (3.3 yd.) CO2 hose 4/6 non-return valve usage instructions Tip: The seramic pH Controller is also ideal for operating calcium reactors and dosing pumps.

Simplified Nighttime CO2 Supply Shutdown When paired with a timer, the sera CO2 solenoid valve allows for automatic and accurate control of CO2 shutdown during the night or at any desired time. This valve is compatible with both existing and new pH-controlled CO2 fertilization systems. Be sure to install a CO2 pressure reducing valve between the sera CO2 solenoid valve and the CO2 gas cylinder.

Kickstart Your CO2 Fertilization JourneyCarbon dioxide (CO2) serves as a fundamental nutrient for plants and helps maintain a slightly acidic pH level, which many aquatic plants and fish thrive in. The sera CO2-Start fertilization system is designed for easy setup and use. It's perfect for the widely used smaller aquariums, accommodating up to approximately 120 liters (31.8 US gal.). The sera CO2-Start includes a discreet sera CO2 diffusion reactor along with the necessary sera CO2-Tabs plus. This user-friendly and straightforward CO2 fertilization system can be seamlessly integrated into your aquarium, making it accessible for beginners with no prior experience.

CO2 fertilizer tablets designed for the CO2 diffusion reactor sera CO2 Tabs are effortlessly inserted into the designated slot of the CO2 diffusion reactor. When they come into contact with the water in your aquarium, each tablet dispenses around 100 ml (equivalent to 2,500 bubbles) of CO2.
