Salinity to 1.024, need to raise it. Safest fastest method?

My 120 (liter) is 107 gallons total system volume. 90 in the tank and, of course, 17 in the sump.
This is up from 70 gal to 90 gal as of 2009 models.

Not "high" but def. elevated, but so does Guillards F/2. Copper is crucial in their growth, and yours in fact. A lot fo what we are scared of is actually needed by life. You can't feed with out PO4 being in the food, etc.
