Salinity survey

[PjFish]

On my tanks with no ATO a point or two lower then NSW gives me a buffer zone since their topped off by hands to a mark or blue tape on glass. Have seen no health or growth disturbances in corals or fish in the tanks that run a bit below.
Plus I don’t have salinity probes or tank controllers yet to get alerts or can easily glance at. I do have several wify inkbirds temp controllers that i get alerts though if needed.

Don’t know if it counts but my salinity is steadily kept at 0.000

I mean when you add the saltwater to the tank and after addition the final reads at say 1.024 instead of 1.025. Do people fiddle with it to get it exact or just leave it because its hit within a specific range of +\-.001.

I don't have the issue of matching it any more, I make sure tank is at proper levels and topped off before I do the change. The salt water I plan to add I also ensure it matches the tank. If I adjust anything its the water i'm going to add not the actual tank. I also put the water i'm adding next to the bucket I drain the tank in so I know I take out and add roughly same amount.

I do.

Clarified my statement: I will adjust sometimes over days to get it to my traget salinity.

I get NSW from high tide so I know at a
Minimum the PPT is 33(1.0249 sg) -
I use a hydrometer and as long as the water is pretty much in the middle of the indicated blue range (all good-last reading 1.025)

My target is 34 to give me wiggle room for evaporation. Forgive me, but I can't remember who here gave me a 33-35ppt range. I think it was @IOnceWasLegend but my memory is not too good.

Running at higher PPT / SG means more of the major and trace elements.
