Real quick, favorite master test kit?
I'm thinking of going with this http://www.amazon.com/API-Freshwater.../dp/B000255NCI
Looks simple, nice price, ect. Any recommendations? I assume that they're mostly all the same. Also will buy the Kh test.
Trained in EMS, I can save a person from death and/or injury. I cannot, however, save a man from his own stupidity.
