Salinity

[Cigarman]

after emptying skimmer cup a couple times a week since setup salinity has dropped from 1.026 to 1.024. I know it’s not critical but short of adding saltwater to sump is there another way to get salinity back up a little. Since I have to top off ATO every 3 or 4 days, i was thinking about just adding saltwater to ATO on next refill. Will that work?

I would just top off with saltwater until it's back to what you want salinity at. The return to regular top off.

Is the skimmate coffee brown or lighter (vegetable oil)? If lighter you might need to adjust the skimmer.
