*Calculations based on the following application rates: Dry salt 30g/m2, Pre-Wet 17g/m2, Brine 35ml/m2. With a Pre-Wet system the application rate is significantly lower, as the pre-wetted salt bonds to the ground and immediately start breaking up the ice.

|100 gal||93 lb||147 lb||254 lb|
|150 gal||139 lb||221 lb||380 lb|
|200 gal||186 lb||295 lb||507 lb|

|350 gal||325 lb||516 lb||887 lb|
Add 147 lb of rock salt to 100 gal fresh water to get a 15% solution. Make sure that the volume of your mixing tank is larger than 100 gal.
These proportions are only approximations and rounded values. Other factors, such as the purity of the salt and the current water temperature may also affect the solution %. Determine the exact concentration of the brine liquid by using a hydrometer.
