Use the numbers from your label and instructions. We check the math. We do not tell you what to take or what to mix.

Looking for BAC water?

Check the product instructions first. A link is not advice to use it.

What to have ready

Start with the instructions for your exact product.

  • The right liquid. Use the liquid named in those instructions. Not every product uses BAC water.
  • A way to measure it. Check the scale and the marks on your device.
  • A record of your numbers. Keep the label and your result together.

The supplier’s water is for lab research only. We do not decide which product you need.
