help fish start dying

Hydrometers are usually inaccurate. They tested salinity with a refractometer at J&L. 1.028 is quite high. Should aim for 1.024-1.026.

If you need one, I have a spare Brand New Refractometer I'm selling for $35. I knew a local reefer who completely wiped out her tank because her 4 hydrometers were all off and by the time she checked with my refractometer, her tank's salinity was 1.012 or brackish.

Ugh... that sucks. It's also a mistake I've made. I let my little guy play with the refractometer a few times and forgot to check calibration of it after. It was quite low, reading 1.019 when it should have been 1.026. Luckily everything was okay but I let it go on for far longer than I should have. Hopefully that's the worst mistake I make with this hobby...

OMG!

That's your main problem. Flush that thing ASAP. Google "cuke nuke".

Do more massive water changes. Run lots of carbon.

Buy some test kits and learn how to use them. Either the LFS stressed that cuke or you did. If you did, you still have secondary issue(s) like the improper acclimatization of that cuke and/or poor water conditions.
