Numbers: Mine and PoolStore

[waterbear]

CAn't find much out about the PinPoint water analysis system other than that it was by Avecia and that Arch Chemical bought out the division of that company that made it.
Here is a link to Ben's online SI calculator if you are interested

The page will show a lot of errors until you plug in all the values and hit the submit button.

Edit: once again this illustrates that computer assisted testing is prone to errors because the computer it 'dumb' and is ony crunching the numbers put into it! There is no substitute for knowledge and human insight when it comes to water testing, IMHO!
Trust your own numbers!
