If you have an alkalinity test set it would be an easy check. If your alkalinity tests higher in the new water than the old water you can pretty much confirm a dangerous increase in salinity.
IMO the floating bulb type hydrometers are great followed by conductivity meters. Refractometers are very good when used with a calibration fluid. Swing arm hydrometers should be banned.

Sorry for your losses
Thanks guys thanks for figuring this out. I'll be ordering a Refractometer tomorrow I knew SG changes could be a problem and I really flipper that SG meter hard until all bubbles were off the arm and if I got a questionable reading I always took another reading but I guess there's just to much room for error with the SG meter thanks againI think we found your problem. If the SG increased a little too much then that could be a problem. those swing arm hydrometers are pretty much useless junk unfortunately.
