Where can I get hold of Richards spread sheet?

[chem geek]

Many charts are in the first post or referred to in links to other posts in this thread and the link to the spreadsheet is near the end of that post or may be found here (the link in the post is to a ZIP file while the link I put here goes directly to the Excel spreadsheet). It is NOT for novice users. I use it to calculate pool water chemistry. Michael Smith's BleachCalc that you can find at this thread is much easier to use.
