It turns out, the simplest solution is sometimes the best, I have discovered what was causing it, and it is embarrassing. Despite measuring and marking when I do my weekly water changes.... I was overfilling my tank by a few gallons which was leaving salt behind.A good hydrometer should be all you really need to reference off, in the long run! — I seem to recall that many reefers around here like the Tropic Marin hydrometer; test your water in a graduated cylinder or other container that isn’t just flowing tank water!
When doing my water change this week I paid extra attention for hours and noticed that the line in my sump didn't go back down to 7.5 inches but instead hovered at 8. SOOOOO I have been putting too much saltwater in, it evaporates, the ATO doesn't kick back in because it shouldn't until 7.5 inches and then leaves the salt behind. Embarrassing.... but I did notice it this week and siphoned out the extra until the ATO kicked back on.... so that should stop the creep this week and now I know how to fix it going forward :( now to get my salinity back to where I want it over time lol. So embarrased
