Thanks! I have been a developer for 17 years. Ya know what I just realized? The importance of good copy/ paste skills. The code is similar for all the different chem levels, so I copied it... my mistake was that I did not update a variable. I left it as the calcium hardness range instead of the salt range.
Thanks again!

Good code design avoids the need for copy paste, as it usually comes back to bite you many times
