I've noticed that my salt reading jumps up and down by approx 1ppt regularly on my Apex. It dawned on me that my temperature does that as well, from the heater going on and off so I used the overlay feature for the first time in the Apex graphing interface and found this very tight connection between my heater and salinity reading. It seems that when my heater is on, the salinity reading drops, and vice versa. I am using a Finnex Titanium heater if that matters, since it is metal.
Curious if others experience this as well and if it's a concern - e.g. is there stray voltage in the tank that could be a problem?
