I have a Korallin C1502 calcium reactor. Noticed my pH had dropped noticeably over the last 12 hours or so, and when I went to investigate I realized I had zero CO2 bubbles. Even opening up all the CO2 valves all the way produced nothing.

So I dismantled everything from the solenoid to the point where the CO2 is injected into the reactor. All individual tubes are free of any blockage. When I take the tube off the place where the CO2 enters the reactor, water flows out so I know the pump on top is working. Water is flowing out the outlet just like it should, and there is zero gas build-up inside the reactor. The CO2 is completely full, and it spews CO2 when nothing is connected to it.

Any ideas why I'm getting zero CO2 flow into the reactor?
 
Totally ended up being the solenoid. All I had to do was turn it off and back on again, though, and boom it was working again.
