Salt was from a bucket that I ordered last Feb. I got a couple more buckets that I just ordered 3mo ago but I haven't opened this buckets yet. I might open them up tomorrow and test it too.

That is a good bucket. I expect those numbers at 1.024
If mixed at 1.0264 (35ppt) your calcium and magnesium numbers will be more in line with the RC I know.
1/2 cup of RC in 1 gallon of water will not yield 1.0264
Thats just the way it is made.
You will need close to 3/4 cup of salt in 1 gallon of water to yield 1.0264 Actually its a little less but certainly more than 1/2 cup.
For what its worth, I've tested about 10 different salt mixes and none of them yielded 1.0264 with exactly 1/2 cup of salt mix. Some were a little better than others but thats a test I'm working on for another day.
When you talk cost per gallon, it is good to know how much salt it takes to make 35 ppt. I believe this makes a big difference in the long run.
