Optimize the growth of your aquatic plants and stabilize your aquarium's pH with the Eheim CO2 night shut-off. An effective and economical solution for a healthy aquatic ecosystem.
The EHEIM Co2 24 V Night Shut-Off is an essential accessory for any aquarist looking to optimize plant growth and stabilize their aquarium's pH. 🌊 This solenoid valve cuts off the CO2 supply at night when plants don't need it, saving up to 50% CO2.
CO2 fertilization is essential for aquatic plant photosynthesis. ✨ During the day, they absorb carbon dioxide and release oxygen. However, at night, in the absence of light, this process is reversed: plants consume oxygen. It is therefore pointless, even counterproductive, to continue diffusing CO2 during this period. The EHEIM Co2 24 V Night Shut-Off solves this problem simply and effectively.
Thanks to its high-quality design, this solenoid valve guarantees safe and reliable operation. It is powered by 24V, which minimizes electrical risks in an aquatic environment. 🐠 It is easy to install and integrates seamlessly into your existing CO2 system.
Investing in the EHEIM Co2 24 V Night Shut-Off means choosing a healthier, more beautiful and more economical aquarium. 🌱
The Eheim CO2 night shut-off is generally compatible with most CO2 systems available on the market. It connects between the CO2 regulator and the diffuser in the aquarium. However, it is always recommended to check the specifications of your CO2 system and the night shut-off to ensure compatibility, especially in terms of voltage (24V in this case) and hose diameter.
Installing the Eheim CO2 night shut-off is relatively simple. Simply connect it between the CO2 regulator and the diffuser inside the aquarium. Make sure the flow direction is correct (usually indicated on the product). It is advisable to disconnect the power supply during installation and check the tightness of the connections after installation to avoid CO2 leaks. You will also need to connect it to a timer (not supplied) to set the opening and closing times.
Using a CO2 night shut-off has several advantages. Firstly, it saves CO2 by cutting off the supply during the night, when plants do not need it because they do not carry out photosynthesis in the absence of light. Secondly, it helps to stabilize the pH of the water, as adding CO2 can lower the pH. By cutting off the supply at night, excessive pH drop is avoided. Finally, it can improve the health of fish and other aquarium inhabitants by maintaining more stable conditions.
