Fresh fills, spring start-ups and a pool that looks wrong
A sample is worth bringing for a hot tub fresh fill, for regular balance checks, and for troubleshooting when something is off and you cannot say what. It is also the first step for a spring pool start-up, for balancing a pool mid-season, and for the pre-winterization test before a closing.
Cloudy water, a smell, or skin that itches after a soak are all reasons to stop guessing and bring a bottle. The result tells you what the water needs before anything is added to it.
