Reef Chemistry Question of the Day #254
Most of us know that the pH in a reef aquarium can be impacted by the carbon dioxide level in the air around the aquarium.
Suppose that you are an average 70 kg man (wish I was ) and you are alone, resting on your couch watching TV in your living room.
The room is 10 feet by 20 feet by 8 feet high.
Approximately how long would it take for the carbon dioxide level to double from a starting point of normal air (350 ppm CO2)?
A. 6 minutes
B. 66 minutes
C. 666 minutes
D. 6,666 minutes
Assume no air exchange from outside the room, or into your reef tank.
(as an aside, this doubling of CO2 could potentially drop your small aquarium pH by 0.3 units; do not use this result since it doesn't help answer the question)
Good luck!
