So I have continued to experience a problem with the probe. Even placing the probe in an area of high flow shows a slow steady decline in readings. I understand the micro bubble theory but it renders the probe as an unreliable and ultimately a mostly useless piece of equipment. If I want a reliable reading it requires me to remove the probe, shake it off, put it back in the water and wait for it to stabilize. This does not fit with the intended design of a continuous monitoring probe. I am not sure how to resolve this. I will most likely contact support directly or try posting on R2R.
