Hello I've noticed this morning that my salt readings according to Apex have drop down to 28. And are fluctuating up-and-down a point or two. They always held steadily at around 34 and I checked this morning with my Milwaukee meter and it's around 34. The photo shows what Im talking about on the right side. Do you think this is a probe going bad? The connection is not loose. It's about a-year-old.
