Our guide to looking after your hot tub

When you purchase a hot tub, keeping it clean and free of harmful bacteria is crucial for a safe and enjoyable swimming experience. Sanitisers, pH adjusters, and shock treatments are the essential elements that ensure your hot tub water is kept safe. This helpful article will walk you through every stage of the best way to care for your hot tub.

Sanitiser

To prevent bacteria development, your hot tub will need to be treated with a sanitiser. Germs can multiply quickly in warm climates, so ensure that the sanitiser is kept at a safe level to guarantee that any bacteria in the water is destroyed. Chlorine and bromine are the two most common sanitisers for keeping your hot tub clean. As chlorine is the most cost-effective and fast-acting sanitiser available, it is the preferred choice among hot tub users. Chlorine comes in the form of granules or pills. Alternatively, some people choose to use Bromine, however it is more costly and slower acting, which means it takes longer for a reading to appear on a test and can cause the water to become murky. You can easily determine the level of sanitiser in your hot tub by dipping in a test strip about 12 inches below the water level. The general rule of thumb is that chlorine levels should be between 3-5ppm and bromine levels between 2-5ppm.

pH Level

The pH level refers to whether or not your water is acidic or alkaline. The pH scale ranges from 0 to 14, with 7 being the neutral value. You must ensure that the pH level is between 7.2 and 7.8, otherwise you’re likely to run into problems. When your pH levels are too low it can lead to corrosion of components, skin & eye irritation, and impede the efficacy of the sanitiser. On the other hand, high pH levels can cause a scale build up, cloudy water, and irritation to your skin & eyes.

Shock Treatments

On top of using a sanitiser, it’s recommended to apply a non-chlorine shock treatment every week to oxidise the water. These types of shock treatments are required to break down Chloramines. The combination of sanitiser with impurities such as sweat or dead skin, chloramines forms, which must be broken down. Shock treatments are also vital to kill bacteria as some types are sanitiser-resistant. Shock treatments are the best way to remove organic compounds which can accumulate in the water, making it look murky.

Water changing

Water can only be chemically treated for so long before it becomes clogged and needs to be replaced. Depending on use, we recommend replacing your water every three to four months. To ensure that your pipes remain clean, we’d also recommend using a pipe cleaner before you empty the tub. This will remove any grime from the pipework, whilst loosening any calcium, which will then be rinsed away with the drained water.
