Got the new controller in this morning, set it up to see if it works and SNAP, the solenoid opened. It's pretty loud every time the solenoid opens, not so loud when it shuts off. After testing, I turned the unit off and went to work. Came home and fired it back up. I had to do the initial setup of fine tuning the regulator to pump in enough co2 upon start up and purge the co2 reaction chamber of water within 2-3 minutes. This took me some time to do and had to purge the co2 reaction chamber of co2 multiple times to get the regulator dialed in. The unit has been running for about 5-6 hours now. I have a 10lb tank and started at 100 PSI, I'm now down to about 91-92 PSI. I'm hoping this huge drop in pressure is due to me purging the co2 reaction chamber of co2 multiple times during initial setup, otherwise, this unit is a gas hog. I also completely shut off my GHL doser and set the KHG to test every single hour. Below are the test results after I shut off the doser.

I tested the effluent of the reactor for the heck of it and it maxed out the hanna checker at 300ppm.
