The co2 controller is a lot more responsive. I set the solenoid to turn off if greater than 42 ppm and turn back on at 40 ppm. I wish I have a clearer log of what's going on but it seems to be on initially for 2 hours, then off an hour then on for .5 hour and off .5 hour subsequent hours.

The fishes are a lot happier. No more late pearling but that's ok as long as the plants get their CO2.
There is slight pearling so the plants are happy too.
