2. The essential notes when using the best hot tub sanitizers: 

According to many people, when it comes to chemistry, it is not totally good. This notion is reasonable! However, if you know how to balance the using of sanitizers, it is not only effective in cleaning your hot tubs but also is critical on the economical side.

  • Checking the balance of the hot tub’s alkalinity, pH level, and the hardness

A number of new hot tub owners are familiar with throwing all the chemicals they buy in their hot tub. This is obviously a mistake because this action can lead to hours of frustration. The chemicals of the hot tub can freely interact in ways that you cannot control. As a result, if you do not balance your hot tub from the beginning, you will by chance limit the effectiveness of sanitizing agents, shock treatments, and clarifying products later on.

  • Deciding suitable sanitizers to your need 

It is true that chlorine and bromine are the two widely-used types of sanitizers in the line of substances applying for the hot tub. For those who are finding a product with a fast-acting sanitizer and decontaminating agent, Chlorine is your best full choice. Moreover, if you want to test the water, add the desired amount of chlorine and rest a short time later to reach the perfect concentration, chlorine will work well.

Bromine - by contrast – requires you a bit of patience, but it can be effectively in the first times of using. Besides, the long-lasting maintaining after using bromine may make you surprised! After waiting a while and trying to achieve a bromine level of 10 ppm, you will witness that your hot tub will be completely cleaned.

  • Making shock treatments weekly

Making shock treatments weekly: Whether using chlorine or bromine as your sanitizer, it is advisable to shock your hot tub at least every week. The best time to shock your hot tub is right after using it so that the bacteria have no chance to irritate your skin, as well as reduce its effectiveness. More importantly, making shock treatments also helps you to dissolve residues, oxidize sanitizers, and remove chloramines or bromines as well.

3. The outstanding standards of the best hot tub sanitizer: 

Do not contain uncomfortable strong smell

The unpleasant odor is the most barrier that a great deal of chemical products copes with. Nowadays, there are some products which offer the smell clean, but others, the scent is harsh and doesn’t mesh well with a relaxing hot tub experience. Therefore, for the customers who want to choose a best hot tub sanitizer for their own, it is necessary to consider this criterion.

Do not irritate eyes

In reality, the traditional hot tub sanitizers often irritate the eyes; making them feel dry and scratchy and even appear red after a long time period of exposure. So, if you don’t want to experience these eye symptoms, you must be careful in choosing a best hot tub sanitizer.

Be safe for the skins, even the sensitive skin

Swimming preferences are common interests of everyone, no exception for those who have the skin are quite sensitive to the chemical. If a hot tub sanitizer may pay much attention to this standard, it is truly the best hot tub sanitizer you are seeking.

Do not have the bleach effect

One of the bad circumstances that most of the hot tub sanitizers gets is the bleach effect. There is no strange when witnessing lots of unexpected cases due to the bleach effect. Imagine that a hair color which are changed its color after soaked in chlorine for a long time! Or even your swimming suit may be faded by the time! Thus, the best hot tub sanitizer should provide the customers a peace of mind.
