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.

Essential Hot Tub Chemicals

To keep your hot tub water clean and safe for use, you need to add a variety of chemicals to your hot tub regularly. Here are the essential hot tub chemicals you need to keep your hot tub well-maintained:

Hot Tub Sanitisers

Sanitisers kill bacteria and other harmful microorganisms in your hot tub water. Chlorine and bromine are the most popular hot tub sanitisers. Chlorine is the most common choice, and you can use chlorine granules or tablets to maintain the chlorine level in your hot tub. Bromine is a good alternative if you prefer sitting at a higher temperature, as it can stay at a stable temperature even when the heat is up. You can use bromine tablets or granules to sanitise your hot tub water.

Hot Tub Shock

Shocking your hot tub is an essential part of hot tub maintenance. Shocking your hot tub means adding a large dose of sanitiser to kill any bacteria and other microorganisms that may be present in your hot tub water. Shocking your hot tub once a week is recommended, or more frequently if you use your hot tub more often. You can use chlorine or non-chlorine shock to shock your hot tub.

pH Adjusting Chemicals

The pH level of your hot tub water should be between 7.2 and 7.8. If the pH level is too low, the water can be acidic and cause skin irritation, and if the pH level is too high, the water can be alkaline and cause scaling. pH adjusting chemicals help to keep the pH level of your hot tub water balanced. You can use pH increaser to raise the pH level or pH decreaser to lower the pH level.

Calcium Hardness Increaser

Calcium hardness increaser helps to raise the calcium levels in your hot tub water. If the calcium levels in your hot tub water are below 100 ppm, you should use calcium hardness increaser to raise the calcium levels. If the calcium levels are above 250 ppm, you should use a scale control product to prevent calcium from solidifying on your hot tub's shell and internal parts.

Hot Tub Line Flush Cleaner

Over time, the plumbing in your hot tub can accumulate debris, oils, and other contaminants. Hot tub line flush cleaner helps to remove these contaminants and keep your hot tub plumbing clean. You should use hot tub line flush cleaner every three months or whenever you drain and refill your hot tub.
