roughly...
1/2 cup salt in 1 gallon = 3%, the concentration for a dip.
1/2 cup in 10 gallons = 0.3%
1/2 cup in 30 gallons = 0.1%
10 x 1/2 cup or 5 cups of the course rock salt used in water softeners will give you
about 0.1%

This is really basic, but can someone tell me how many CUPS of salt to add to a
300 gal pond?
