I have seen many threads about the salinity probe, but not one regarding this specific phenomenon. My entire system is new, the probes have been in the tank for about 3 days. I calibrated the pH probe yesterday but have been holding off on the salinity probe until readings stabilize. When I first placed the probe it was very low, I was able to give it a gentle shake and clear out some air bubbles and it quickly raised to a more expected value around 35. Since then it has been gradually increasing. It sways with temperature but overall the trend is still increasing. Is this expected behavior for the probe? How long do people typically wait to calibrate the probe?
