Check out these readings from my conductivity probe as seen on my profilux touch.....this has been happening now for the last couple days.....salinity level slowly drops down low and then all of a sudden will be back at normal....my norm is 53ms and you can see in the first pic that it is almost at 52ms...yesterday it was at 51.8.... There is no water being added to the tank and refractometer shows no change so it has to be the probe.....has anyone experienced this before?? Is it just a matter of recalibrate the probe?
