Salinity changed..

[Notsolostfish]

My tank is 150G with 50G sump. Water volume 150G. For 9 months now been testing weekly and biweekly. And salinity is 1.026. Today i tested and it dropped to 1.025 according to my hydrometer. And my milwaukee ma877. Should i be worried? My redsea ato working like it should. Or is that the skimmer lowered the salinity?

Your skimmer probably just lowered it over time. Its nothing to worry about and we all have to do minor adjustments to compensate for things like skimmers that remove saltwater from our tanks slowly. If you don’t change water often, a good trick to slowly adjust between water changes is to put some salt in a jar with holes in the top and submerge it in your sump. The salt will dissolve slowly over time to get you back on target.
