Calibrating an Apex salinity probe

Looks pretty good to me Shelly, what's so problematic about it exactly? It's actually pretty stable, just the resolution is misleading. Set your ATO to activate less frequently and it'll look a little better.

The 18th, 19th, and 20th are what I expect to see on the graph. I consider anything else unsatisfactory. Those days are pretty much bang on, as the degree of temperature fluctuation I allow in the tank has an effect on conductivity.

What probe are you using? The Neptune probes seem to have issues remaining calibrated, and they are affected by microbubbles and debris quite badly.
