Most pool owners test too infrequently and then wonder why problems sneak up on them. Testing 2-3 times a week during swim season is the standard, but the real answer depends on your pool's situation. Here's a practical breakdown of what to test, how often, and when you actually need to test more.

Pool calcium hardness should sit between 200 and 400 ppm for most pools. Too low and your water eats plaster and equipment. Too high and you get scale on everything. This guide covers exactly how to test, raise, and lower calcium hardness the right way.
