After reading lots of threads about chenistry and testing, the one common theme is that pool store water sampliing can't be trusted. My question, or questions, are:
What method are they using?
Is it a standard kit, or setup?
Are there any standards used, or acredditing agency to insure accuracy?
If not, why not?
I'd ssure hate to have these guys doing the lab work at my local doctor's office. It could kill a person.
