Unfortunately, my real world example doesn't fit this model, which would be
why I threw in another data point. My CO2 consumption rate seems to be based
on KH, lighting, plant density, growth rate, losses from open tops and
wet/dry filters, and reactor efficiency. I didn't start logging CO2
consumption until 5 years ago so my data may be incomplete, but changing any
of these variables has demonstrated an impact on CO2 consumption here.
