Thanks, EnoNut, for testing it on your Mac. I'm glad it's working for you
and potentially for other Mac users.

Steve, thanks!

I have a barrel that I needed to add sulphite to, and the calculator
nailed it! Love that you can specify PotMet, choose crystal, or
solution and concentration to calculate qty needed.

I'm a Mac user on Firefox and it worked great after I 'allowed' Java
scripting on that page.

Good Job! I'll definitely bookmark your page.
