I used oxygen (O2
) and carbon dioxide (CO2
) test kits when I went collecting fish from the wild. This was more for the scientific side and recording the different levels in the water. When I monitored my aquariums with them, they always had high O2
and low CO2
. This was due to my tanks having airstones bubbling away.
If you add CO2
to an aquarium, you should monitor the levels to make sure there isn't too much CO2
in the water. Fish and other animals can die if there is too much CO2
even when there is oxygen available as well. The human race is about to experience this first hand in the next 20 years when the CO2
levels in the atmosphere pass a critical threshold and we all start dying from lack of oxygen and too much CO2
