Test strips, chlorine-free, 50 pcs

Set of 50 strips for testing the pH value / alkalinity of water.

An indispensable tool for maintaining the water quality in your outdoor spa.

Alkalinity is preferable to acidity in the water. A pH value of 7 means that the water is neither acidic nor basic. In the spa, the pH value should be 6.8-7.2*.

A value below 6.5 or above 7.6 is not advisable.

Guidance

It's that easy to measure pH value and chlorine content:

1. Hold a strip horizontally in the water for about 5 seconds.

2. Hold the strip still over the water for about 10 seconds.

3. Compare the colors with the table on the box.

*According to the Executive Order on swimming pool facilities etc. and their water quality, Appendix 1, the pH value should be between 6.8 and 7.0. The value must not be below 6.8 and never above 7.6. Water in Denmark is calcareous, and therefore has a relatively high pH value. The use of pH-increasing agents should not be necessary. You can optionally replace some of the water with tap water.
