How are you measuring salt?

Right now I use a measuring cup and just count them out. I normally mix 20-30 gallons at a time so 10 cups for 20 gallons or 15 cups for 30 gallons. Gets me close then I measure and adjust from there.

I have old IO buckets marked at 1gallon increments, fill to the 5 gallon mark with RODI and add 480g of IO to get me close to 35ppt. Once mixed I adjust as needed.

Sorry, that should be 850g of IO.
