Recalibrate my refractometer today and noticed my salinity was 1.022 or 30ppt. Only my Duncan looks a bit ticked but everything else looks fine. Should I raise asap or just top off with salt until I hit 35 or 1.026? Also, feel a little silly, I'm sure it got low from my skimmer I never thought about replacing the saltwater pulled and treating it like a water change.
Thanks!
Thanks!
