My Milwaukee solenoid was sticking in the open position and allowing CO2 into the tank regardless of the pH controller. THe controller was set at a pH of 6.8 but keep sticking open. I called Milwaukee to see if I could get a new solenoid, they sent one (used) and it was worse. I followed set up directions precisely (no back pressure as recommended) but today I came home to a pH of 4.2 (5 lb CO2 bottle was 3/4 full) and all dead livestock.
Can anyone recommend a good, reliable CO2 system?
Thanks,
