Helps detect stress on fish caused by rapid pH shifts, which result from low KH levels and helps aquarists duplicate the natural habitat of their fish.

api brand is the only test kits I trust and use. I had some questions about this test kit as I had not used it before and Jeff @ JLA. was prompt in answering them for me.
