Active Oxygen Testing

50 Active Oxygen test strips.

You should test your spa an hour after application of each Active Oxygen tablet and prior to entering the water to ensure that the Active Oxygen level is in the range 5.0 - 10.0 ppm.

Simply dip a strip into the spa water and compare with the colour chart.

These strips test for Active Oxygen, pH and Total Alkalinity

Although water testing isn't necessarily needed for eco3spa, for added peace of mind, you can test for the Active Oxygen sanitiser level in your hot tub prior to use.

This handy, flip-top container contains 25 Active Oxygen test strips.

Supplied in an aluminium container which guarantees 3 years test strip life if kept sealed.

NB: These strips do not test for Total Alkalinity and pH since the efficacy of Active Oxygen as a sanitiser is not dependent on the pH balance balance of the water.
