I have set up the Profilux 4 to monitor conductivity with a goal of 53mS. I have it assigned temperature compensation as "Temperature 1". I have ATO with Tunze and Temp stable at 26 degrees. When I set up the probe the conductivity reads 53.2 and slowly drops over a day or two to where it is now 52mS. I have checked the aquarium (Reefer XL 450) for leaks and it is intact. I haver looked for salt creep and find none.
I therefore am concluding that there is an issue with the probe or software reading it. Can I get assistance with this?
