Hi, not to be a damp cloth here, but this wont work.  Water chemistry is 
a precise science and require precise measurements.  I researched this 
for the last two years and haven't find a affordable tool that blind 
pool owners can use.  The only electronic instruments out there capable 
of doing some of the required measurements are damn expensive, and don't 
do all that's needed, so my personal advice is to understand your pool, 
get the water 100% right, with sighted help, and then do the basics to 
keep it well maintained.  If the ph, alkalinity, stabilizer levels and 
chloreen is right to start off with, you'll learn quickly what to do to 
keep it there.  If it is not in the right parameters to start with, and 
you go about it the wrong way to fix it, you'll spend the whole year 
keeping on adding all sorts of chemicals without ever getting it right, 
so start off by reading everything you can get on how water chemistry 
works, and why certain things need to be done certain ways.
I'll look if I can get good references to post to the list, but first 
I'm off to work.
Cheers,
Matthys.
