For fun, I ran the app. The lights are off in my low-tech.

There's a time stamp (h:m:s) with the co2 ppm.

Serial Up!

19:7:47 -
Co2 ppm = 10.01

20:0:0 -
Co2 ppm = 11.05

21:0:1 -
Co2 ppm = 12.16

22:0:0 -
Co2 ppm = 12.88
Looks like the trend is the CO2 builds up till the lights turn on. Who knew there was a natural CO2 generator in my tank .... Actually, I knew.
