is it possible for salinity to rise while using an air stone in a DT? Trying to figure out why my salinity went up from 1.024 to 1.025 in a week with ATO. My DT is a 10 gal nuvo10 so I don’t have room for parameter swings. Thanks.

If the water level is truly unchanged, salinity can only rise by adding salts.
That said, the change you see could be within the testing accuracy of your device.

Ok this might the answer. I just remembered this. I did a water change before this past Sunday 10% my salinity before was the water change was 1.024 and when I refilled the water my new water was at 1.026. But from Monday & Tuesday it was 1.024 and today it jumped to 1.025.
Could that be the reason? Hopefully I made sense here lol

If you are using the Milwaukee MA887 Digital Salinity Refractometer, then it only claims accuracy to +/- 2 ppt (PSU), which makes your two measurements (1.024 = 32 ppt and 1.025 = 33 ppt) equivalent.
