Anyone with a refractometer I can borrow in midtown Manhattan?

My hydrometer broke in the process of switching tanks, bought a new one Fluval hydrometer from Petco but the readings are off the charts. I tried a vinegar bath for an hour but not much better. Anyone have a refractometer I could borrow for a day? I ordered one on Amazon but it wont come til Thursday. I have two half-full tanks in my living room! Happy to give you a $100 cash deposit while I borrow it...

Mine is not calibrated but you can borrow it if you want.

Thank you! Petco actually had one in stock - shockingly. Appreciate the offer though.
