Symptoms of high pH include scale on surfaces and cloudy water, poor sanitiser function and the need for frequent filter cleaning.

Symptoms of low pH include skin and eye irritation, excessive sanitizer use and, more seriously, corrosion of the pumps and heater and pitting or etching on the pool or spa surface.

Maintaining the Total Alkalinity within the correct range is the key to water balancing. Low Total Alkalinity will cause hot tub water to become corrosive and potentially damaging to the equipment and surface, it will also cause the pH to fluctuate widely.

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.
