Often times, hot tub and spa owners take for granted the importance of proper sanitation. They usually use detergents to clean their hot tubs and spas. Take note, bacteria easily thrive and reproduce in wet areas, so sanitizing your hot tub using the right chemicals is the most important maintenance you can do.

There are many sanitizers available on the market. However, not all are effective enough to kill the harmful bacteria that usually grow in hot tubs and spas. It is recommended to use EPA approved, & specifically formulated Sanitizers for spas & hot tubs.

Before sanitizing your spa and hot tubs:

It is a must to test the pH level and calcium level of your water before adding any sanitizing agent to your hot tub. A good quality test strip is highly recommended. Test strips are formulated to measure the levels of the different sanitizers like bromine, chlorine, biguanide or mineral content in your hot tub water. They are easy to use.

Here is a list of some common types of sanitizers:

1. Chlorine
This is the primary sanitizer used in pools. In hot tubs and spas, chlorine comes in different concentration: granules and tablets. These concentrated form of chlorine are specifically made for hot tubs and spas. Take note not to tamper the level of concentration in sanitizing your hot tub with chlorine.

2. Bromine
Just like chlorine, Bromine is an effective sanitizer and comes in the form of nuggets or granules and tablets. Sodium bromide is activated using an oxidizer like chlorine or Potassium Monopersulfate shock. BCDMH is another bromine product, which is a self-activating chlorine bromine combination. Bromine do not produce strong odor like chlorine. It does not “gas off” when use at temperatures higher than 98 degrees.

3. Biguanide
Biguanide can kill bacteria by attacking the cell wall. It is a non-chlorine, non-bromine sanitizer and like bromine, it does not “gas off” at hot tub temperature.

4. Ozone
Though not a sanitizer, ozone as an oxidizer helps reduce the work of the sanitizers. It lowers the level of sanitizers needed to keep the spa and hot tub clean. The process starts with the use of an “ozonator” that is commonly equipped in most hot tubs. However, the ozonator process still needs to be supplemented with a low level of sanitizer like chlorine, bromine, biguanide and other mineral systems.

5. Enzyme
Natural enzyme cleaners help hot tub and spa owners reduce spa maintenance because they break down oils, lotions and organic materials that usually cause odors, scum lines and cloudy water.

6. Boost (Shock)
This is a powerful non-chlorine, liquid shock sanitizer that is formulated to break down oils, lotions and other organic materials.

Hot tub and spa owners should buy sanitizers only at reputable retailers of hot tub accessories, filters, chemicals, lifters, hot tub and spa covers.
