This question is obviously intended for those that live in places where tap water is “safe to drink.”
I live in Southern California, where I’m at the end of a long chain of cities. Occasionally, the tap smells of sulfur, hardness changes, or it tastes… odd. I’m curious about the perspective of people that are directly involved and their reasoning.
Not expensive but it depends on what you want to test. Most of the available tests can be gotten from aquarium supply stores. Got to keep fish healthy after all. Others can be gotten from pool supply companies.
Thank you. :)
