This tool estimates CO₂ pressure needed to fully dissolve given amount of chalk (CaCO₃) in given volume of water.
This form was inspired by article published on braukaiser.com site and by this AHA forum thread.

Notes:

• Tool is available only for registered users.
• Choose units.
• Enter chalk weight and water volume.
• Tool estimates chalk concentration (ppm) and CO₂ pressure needed to dissolve the chalk.
  • Note: calculated CO₂ pressure includes atmospheric pressure. You can set lower pressure (about 1 bar lower) on your CO₂ regulator.
