Prevent waste of CO2 & dead fish
What do you do to avoid CO2 waste and dead fish in your tank? You can manually turn off the CO2 at night. But let’s face it: that’s inconvenient and chances are you’ll forget. That was the case for me 🙂
No, much easier is to simply install an aquarium CO2 solenoid valve. You plug the CO2 hose from your pressure regulator into the connection of the solenoid valve and then you plug your solenoid valve into a time clock and then into the outlet. Now you set the timer according to the time you want it to turn on or off.
Is the power on? Then the LED light goes on and the solenoid valve opens the CO2 supply and the CO2 goes through your CO2 hose to your aquarium. Is the power off? Then the valve closes the supply of CO2 again.
