The patented bottle has a molded desiccant liner, protecting the strips from moisture intrusion and eliminating loose desiccant bags. To keep your pool at its best, test at each end at least twice a week, and test your spa before each use. It's also a good idea to write down your results each time you test, so you can track changes.
