Two of the three fields are required to calculate the empty field.

[Volume of Water] – [% Salinity Change] or [Amount of non-iodized Salt]

The calculator will retain the last field entered and will calculate the missing field.

For example, if you enter Gallons and then go to Amount, the % Salinity will be calculated or if you enter Gallons and then % Salinity, the Amount will be calculated.  *(note 0.1 = 10%)

Salt concentrations will vary; always consult with a professional before introducing any major changes to your ponds ecosystem.
