Increasing salinity with a water change

[Brav403]

My fairly new tank is at 1.023 salinity which I understand is still ok to run but is on the low spectrum. I would ultimately like to bring it up to 1.024/1.025.

I am looking at doing a water change in a day or two (first one since adding livestock) and wondering if it would be possible to make up a batch that is at 1.024 for a 10% water change.

My tank is a 125L/33gal. Or would I just be safer to do the water change at 1.023 and then add some extra saltwater to my ATO over a few days?

@ 10% you should be fine.
Raising salinity should not be done rapidly.
You can however drop salinity like a rock.

Best way to raise salinity is to replace evaporated water with normal salinity sea water until the salinity is at your target.

It is both cheaper and more gentle than doing it by water change.
