Went away for a week, came back to 1.60 salinity...??

I'm inclined to agree that there was a problem or error in the reading. A 95 gallon with 60 gallon sump, let's assume around 120 gallons of water in this system, would require in the order of 240 cups of salt to go from 1.000 to 1.025 (so 240 cups for a jump of 0.025). Correspondingly a jump to 1.060 from 1.025, a difference of 0.035 would be in the ballpark of 336 cups of salt.
