No, I'm not using a sump tank. The CO2 reactor is pretty close to the probe -- above the reactor probably 6" away. Should I move the probe to the other side of my tank?
The solenoid does appear to be working properly, but I do not hear it going on/off frequently.
I don't think the bubble rate is high -- 2 per second. Please let me know if you disagree. I have not calibrated the controller since setting it up two months ago. Will do.
Thanks for the replies,
