You cannot calibrate a hydro. If crud builds upon the float its registering as less. I think they are useless and completely unreliable.
You can calibrate it against a refractometer... I usually recheck mine every few months, and they are still 'dead on' for about a year...been doing this for many years. I give them a quick rinse with fresh water after each use...much easier and quicker to use than refracto

I had similar issue in the past and to raise salinty I would take my auto top off line and put it into a container of freshly made saltwater , to lower I would take out a gallon or 1/2 gallon a day and let my auto top off add fresh ro water. Go with the refractometer for the extra bucks its not worth lives stock being lost and give you a better Idea of your salinity.
In this hobby everyone has their way of doing things. If you are close to Staten Island I would gladly test your water with a refractometer vs the hydrometer would love to see the results.

Thanks. Ill look into getting the refractometer in the near future. Im downgrading to a 10 gallon soon :)
Keeping parameters in check in a smaller tank is much more difficult. I would say keep the tank that you have.

I am back in NYC now but if you need to borrow a refractometer or test kits they are still in Princeton and can make arrangements for you to swing by.

SO everything is fixed now. I lost my utter choas, half of my blue hornet frag, acan frag, all my sps, VDMS, emeralds on fire by cherry corals, and have learned my lesson. Just got an ro unit so definately looking to do a 20 gal water change to better help with the process.

Dont ever change water without checking the salinity of the new water and the tank water. You can't approximate anything, especially not solid salt as the actual density can't be measured unless you weigh it.
