Marimex Spa Test Strips 6v1 - 50 pcs(11305036)

Strip tester - 50 test strips for measuring water quality.
You test: total chlorine, total bromine, free chlorine, total alkalinity, pH and calcium hardness.

Ideal for those who prefer Chlorine as the main disinfectant in hot tubs.
Aquachek's 6in1 test includes testing for Cyanuric Acid, which is particularly important in outdoor hot tubs as chlorine tends to be dispersed by UV light.
Get 6 important results in one test! Just put the AquaChek Spa 6in1 in your hot tub or pool for a few seconds, pull it out and you have a result instantly! The ideal way to measure is to test at least twice a week.

Dip the strip into the water and pull it out immediately.
Hold the strip horizontally for 15 seconds (do not shake excess water off the strip).
Compare the colour of the pH, free chlorine, total alkalinity and stabiliser pad (in that order) with the colour chart on the label.
The best results for the stabilizer (cyanuric acid) test are obtained when the pH is between 7.0 and 8.4 and the total alkalinity should be no more than 240 ppm.

Important Note: When not in use, tighten the cap securely. Use by the date on the cap.

For interpretation of the diagram on the bottle: LOW = LOW, OK = OK, HIGH = HIGH.
