What are your thoughts and experience on this thus far?
Below the port would make it innaccurate. Upstream is most accurate because the water has gone the whole route, i.e., through the tank and filter before reaching the probe. CO2 being in the reactor in neglible since it is being released into bio balls and pushed through into the tank. I have had no problems with the 3 I have been running for over a year now, they are working very well in fact, no calibration or cleaning needed yet......DC
