Hot tub scaling can harm your hot tub and be challenging to get rid of. Luckily, there are several measures you can take to prevent hot tub scaling from occurring.

By doing so, you can ensure that your hot tub stays clean and blue for years to come.


To ensure optimal hot tub function and longevity, it is essential to maintain a balanced pH level. Hot tub owners should regularly clean their filters and ensure that pH levels remain between 7.2 and 7.8 on the pH scale in order to prevent scaling issues.

Adding special hot tub chemicals like Bromine or Chlorine tablets into the water a few times a week can help maintain proper pH balance and prevent hot tub scaling.
