What is aquarium CO2?

Aquarium CO2 is a gas essential for aquarium plants’ growth. It is also used to provide oxygen to fish and other aquatic animals. CO2 is produced by the breakdown of organic matter and released into the atmosphere. Aquarium CO2 can come from various sources, including air, water, and soil.

Should aquarium CO2 be turned off at night?

Aquarium CO2 is often turned off at night, but there are a few things to consider before doing so. First, fish and other aquatic creatures need oxygen to survive, and locking out CO2 can lower oxygen levels in the water. Second, plants also need CO2 to grow, so cutting it can stunt their growth.

It is ultimately up to the aquarium owner whether or not to turn off the CO2 at night. It does not need to be closed if oxygen levels and plant growth are not a concern. However, if either of these is a concern, it is best to continue CO2.
