Thanks for the calculator. It explains ALOT!!!!! since my garage is super hot, I test my salinity @1.023, but whenever I checked the salinity in my tank, it was always @1.024, couldn't understand why... But now this makes sense. I will have to be very careful when mixing during the winter. The garage can probably get as low as 40-50F.
