Part 2. What Are The Different Types Of Hot Tub Shock?

  • Non-Chlorine Shock

One of the common types of non-chlorine hot tub shock is the potassium peroxymonosulfate or the potassium monopersulfate. This non-chlorine shock is not a sanitizer; however, it can also improve the quality of your hot tub water and can help oxidize contaminants that you can find on it. It is recommended to be used for your regular maintenance schedules, and it would also be safer to assume that this one does not and will not disinfect your hot tub water.

  • Chlorine-Based Shock

Sodium dichlor or dichlor can act as an oxidizer and as a sanitizer as well. If you want to immediately address a dilemma in your hot tub water, this is the most common and inexpensive type you should get. If you always encounter a heavy bather load in your hot tubs, and you also notice the presence of too many contaminants, it is recommended to use a chlorine-based shock.

Aside from these two, there are other forms of hot tub shock treatments that you can also use. For a biguanide shock treatment, you should use a biguanide sanitizer. You can use either a non-chlorine or chlorine shock if you have a saltwater tub. It is also needed that you are aware of the compatibility of the shocks that you are about to use in your hot tubs. It is good to know that both chlorine-based and non-chlorine shock are compatible with most of your spa equipment such as ultraviolet, ozone, and ionization.
