A hot tub provides a great, relaxing experience, but over time, the water in the hot tub becomes dirty and contaminated due to lotions, make-up, sweat and dirt. All these contaminants not only make your hot tub experience less enjoyable but could also lead to infections.

It is, therefore, necessary to maintain the hygiene .There are many ways you could accomplish that, but none is as easy or effective as using mineral hot tub sanitizers. On this guide, we will provide you with the following information:

Benefits of using hot tub sanitizers

1. Less chlorine is required

Use of mineral sanitizers reduces the need for chlorine; hence you get to use less of it. The mere fact that you use less chlorine in your hot tub means that you don't have to deal with the disadvantages associated with chlorine like chloramines, odour and harshness to the skin which is caused by excessive use of chlorine.

2. They are more economical

Hot tub mineral sanitizes don't cost as much as bromine, chlorine or other sanitizers. Also, the mineral cartridge is changed once in a few months, depending on the rate at which your hot tub is used.

3. Easy to use and manage

When using mineral hot tub sanitizers, you don't need to measure chemicals before adding them to water. They also eliminate the need to wait before getting into your hot tub; you can add them and bathe right away. Awesome, right?

Limitations of using hot tub sanitizers

1. Might stain your hot tub

Copper is the main element in mineral sanitizers. It is also a common cause of staining in hot tubs. If your water source has a high copper content, then your hot tub is at a higher risk of getting stained.

If your hot tub develops stains due to copper, you could try using a metal sequestrant to prevent it from settling on your hot tub's surface. You should also note that using too much metal sequestrant could make your sanitizer ineffective.

2. You still need bromine and chlorine

Although they are effective, mineral sanitizers are not enough to effectively sanitize your hot tub. You need to add chlorine and bromine to clean the water thoroughly and kill bacteria and viruses.
