im pretty sure most salts it is 1/2 cup per gallon so you should be good. Do you have a hydrometer or a refractometer to check it?

Hmmm, that is just about what I do... but then again I also own 6 hydrometers that I can use to check it after it is mixed.
I'm assuming you have a hydromter... right? If not, buy one tomorrow... or even today... but certainly before you go any further.
1.023 is perfect

That will definitely get you close but I would test it for sure. What does you hydrometer read?

Kida hard to explain, for every 5 degrees in temperature, the salinity that a 1.023 specific gravity reading measures will change by approximately 1 ppt...
For example. a sample with measured at 75 degrees with a hydrometer would read 1.023. That same sample measured with a refractometer would measure a salinity of 32.49 ppt. That same sample raised up to a temp of 80 degrees would be a specific gravity of about about 1.0221. The warmer the sample is the lower the specific gravity reading will be. That is one reason I would prefer a refractometer.
However I am frugal and a hydrometer works just fine...
Thanks,
Scott
