I came across another brewing water spreadsheet today, and I have to say that it is probably the easiest water calculator I have found. It has standard profiles that can be loaded into the sheet automatically as well as the ability to add custom profiles (and save them). Very easy to use and well done!

I am working on an post about using slaked lime to remove high levels of bicarbonate. These are some interesting links that I have come across in the process of doing the research:

More once I can bring it together, but in the mean time I really don’t want to lose those links.
In addition to Jon Palmer’s book this is a great resource for adjusting your water chemistry. VERY simple to use.
