This is the 1st 2144 transplanted on April 12th. The Co2 controller is the little black box in the upper right hand corner.. It will shut off the tank when it gets dark outside. Co2 needs sunlight. It will shut off the CO2 when it gets too hot. Co2 is not used efficiently by the plant when it's over 90 f. It will shut off the CO2 at 1200 ppm. This is approximately enough for efficient photosynthesis. It will turn the tank back on when the CO2 level drops down below your preset amount. I set the low level at 800 ppm. Amazing little "Blackbox".
