Understanding Hot Tub Chemistry

Hot tubs are a great way to relax and unwind, but they require regular maintenance to keep the water clean and safe to soak in. This is where hot tub chemicals come in - they help to keep the water balanced and free from harmful bacteria.

Why Does Your Hot Tub Need Chemicals?

Your hot tub needs chemicals to maintain the correct balance of pH, alkalinity, and sanitiser levels. The pH level measures the acidity or alkalinity of the water, while alkalinity helps to stabilise the pH level. Sanitisers, such as chlorine or bromine, are used to kill bacteria and other harmful organisms in the water.

Without the correct levels of these chemicals, your hot tub water can become cloudy, foamy, or even green. This can be a breeding ground for bacteria and other harmful organisms that can cause skin irritation, eye infections, and other health problems.

What is Chemical Balance in a Hot Tub?

Chemical balance refers to the correct levels of pH, alkalinity, and sanitiser in the hot tub water. These levels should be checked regularly using a test kit or test strips. The ideal pH level for hot tub water is between 7.2 and 7.8, while the ideal alkalinity level is between 80 and 120 ppm (parts per million). Sanitiser levels should be maintained at the recommended levels according to the type of sanitiser used.

Maintaining the correct chemical balance in your hot tub is important for both your health and the longevity of your spa. Too much or too little of any chemical can cause the water to become unbalanced, leading to problems such as skin irritation, equipment damage, and an unpleasant odour.
