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

I thought he meant maybe his SG went up to 1.060 from 1.025 or whatever he normally keeps it at.

do u dose as well? I noticed mine climbed from 1.025 to 1.031. only thing I could put it down to was dosing.
I think specifically it was magnesium. I was trying the whole add tons of mag and hope the algae will die off trick... never got it to work.

Ah specific gravity with a missing zero, makes more sense now. I have no idea how it could get that high without interference. More salt must have been added.

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.

Ime, reef inhabitants become irritated around 1.035 (SPS corals much sooner). I don't trust your refractometer. Do you happen to have anything else around to test with? Even a hydrometer reading would help at this point.
