"I'm hoping someone can help me with this question - can you run CO2 24 hours a day? I'm setting up a new planted aquarium and want to make sure I'm doing it right. I'm worried that running CO2 all the time could be bad for the fish and plants in the tank, but I also want to make sure the plants get enough CO2. Does anyone have experience with running CO2 24 hours a day? Any advice would be much appreciated.
