The Effects of High or Low PH Levels

Are you having issues with your hot tub water? Perhaps skin irritation after going in the spa? Or is your water not quite right? It is extremely important to keep your pH levels between 7.2 and 7.8 - having pH levels that are higher than 7.8 or lower than 7.2 can cause problems not only for the hot tub but also for you!

The effects of a pH level which is too high (high calcium)


• Calcium build up
• Damage to pump seals and other components
• Marks and staining to the acrylic
• Dry, itchy skin and burning eyes
• Chlorine/bromine less effective and the need to use more
• Cloudy water

The effects of a pH level which is too low (high acidity)

In order to avoid this it's important to use your pH test strips to check your pH levels on a regular basis, especially just before getting in.

If you do encounter a problem with high pH, use a pH Decreaser product to get it back within the correct range. If your pH is too low, use a pH Increaser product to raise the level.

Keeping your hot tub’s pH levels correct will create a more comfortable environment, help you avoid scale and calcium buildup, avoid warranty issues and help keep your hot tub equipment free of corrosion.
