So i just finished setting up my apex after 5 hrs lolll. But my only issue is the salinity read 37 ppt when in the calibration stuff now its back to reading 0 should i let it ride for a couple days and check back on it or should it be "accurate" after placement?

Assure all air is out of the probe and it is not in path of bubbles or other electrical current

Someone correct me if I'm mis remembering but I thought in one of the Control Freak YouTube videos Terrence said it takes several days for the salinity probe to condition before it's accurate.

Please let your probes soak in the sump for a few days before attempting calibration. During this time you will likely see the values drifting but this is normal.
Be sure you have removed the protective caps from the pH and ORP probes when you place them in your tank. These probes must be stored wet or they will be ruined. If you ever take them out for storage, be sure to use a probe storage bottle with storage solution or saltwater.
The salinity probe is known to read inaccurate numbers if there are any microbubbles inside the probe, and can also be impacted if the cable is in close proximity to electrical power cords, like for your return pump or skimmer. If possible, route the cable for the salinity probe on the opposite side of your cabinet from power cords.
To combat the bubble problem, I mount my salinity probe submerged upside down so bubbles can float up and out of the probe tip on their own. The only drawback to this method is that Neptune says the cable will become brittle over time if left in salt water. But they don't state how long that takes. I've had mine underwater for nearly 2 years and my readings have been very stable. I also have it positioned where it won't get bumped easily, so even if it is brittle it shouldn't be damaged.
I also calibrate the probe upside down in a probe storage bottle with the calibration solution so there are no bubbles.
If you don't have a probe storage bottle, you can use a small plastic bag with a rubber band to hold it onto the probe, then tip it upside down in the solution.
Hope this helps.
