Absolute cleanest salt???

I will then cease to use heat in mixing water

If I mix water in the garage and the temperature goes down to 50 degrees. Will that be too cold for the carbon carbonate to dissolve?

Why do you heat when mixing?

I let it mix cold until it’s mostly clear, then I turn on the heat. I measure salinity with a Tropic Marin High Precision Hydrometer at 77 degrees. Since my brute is in the garage, I need to heat it up to measure. I could use your adjustment tables, just find it easier to measure at 77 degrees.
