Mark,
Thanks for the reply - I have the calculator but did not even notice the salt calc included with the bleach calc....ooooppss. I just installed it the other day and it is very cool and from what little I have used it has been right on with the calculations and the results, sorry I missed the salt calc on it.

So the now question is what do I need to get my salt test kit to read somewhere around 3000 ppm instead of 8000ppm.

Any ideas?

thanks again
Kevin
