Aquachek orange (active oxygen)

AquaChek Orange tests for potassium monopersulfate (active oxygen), pH and total alkalinity.

To perform the test, simply dip your AquaChek Monopersulfate strip into the water or pool rapidly for one second, and remove it immediately.

You'll get results in seconds.

To keep your pool in tip-top shape, you should test each end at least twice a week, and for a spa, before each use.

It's also a good idea to make a note of your results after each test.
