+1when you look at your refractometer, what is the scale that you see? is it in ppm on the right or are you looking at the left in the decimal and seeing 1.027?

I been using a hydrometer since day one. Tank SPS like crazy. I check At the LFS every month or 2 and it always matches. Them refractometers gotta be tuned all the time tho I heard...Exactly and it seems that you didn't get the best advice from your LFS if they recommend that test kit and hydrometer.
I calibrate mine twice a year just for my piece of mind but its never off. I had two hydrometers when I first started and both of them were 5 points off one high one low will never use one again cause you can't calibrate them you just hope they are right.I been using a hydrometer since day one.

I am doing weekly water changesAt this point I wouldn't dose anything. I would do a 25% water change each week. This would get your parameters back where they need to be. Looking at your tank (or what you have posted) doesn't show a huge amount of corals in there that would require dosing anything extra at this point.
What salt are you using and what is your water change schedule currently like?
And use fritz saltI am doing weekly water changes
My temp is 78I don't think I saw anybody ask about temperature. Is it possible you've got a heater failure?
