What is hot tub Sanitizer and Why Do I Need it?


What is Hot Tub Sanitizer?

Hot tub sanitizer is a chemical compound used to kill bacteria and purify the hot tub water, keeping it sanitary for bathing. Hot tub Sanitizer is delivered in the form of a tablet, granule or powder, all of which dissolve in the water. The most common hot tub sanitizers are chlorine and bromine (with chlorine being the most popular of the two.) Other sanitizers are available such as mineral sanitizers, however these are not recommended for most hard shell hot tubs as they can corrode the acrylic and jet nozzles.

In addition to sanitizer, some hot tub owners use additional measures to further purify and clean their hot tub's water. Some examples of these include silver cartridges for filters (ionizers), UV sanitizers and ozonators. At Direct Hot tubs, many of our hot tubs are fitted with ozonators as an additional method of water purification.

Why Does My Hot Tub Need Sanitizer?

Hot tub water must be sanitized in order to make it safe for bathing. Without sanitization and filtration your hot tub could start resembling something more of a pond than a pool! Sanitizer helps to keep the water free of dangerous bacteria as well as preventing unsightly mould and algae growth.

Hot tubs are filled with water and this same water is used repeatedly until it is time for a water change. How often you need to change your hot tubs water is dependant on a number of factors including frequency of use, the size of the hot tub and how many people tend to use it. As the water sits in the hot tub use after use, sanitizer is vital for preventing bacteria growth between water changes.
