  1. Hot Tub Sanitizer

There are a few types of sanitizers that you can use to sanitize your spa, and these include chlorine, bromine, biguanide, minerals, or a saltwater system. Chlorine is the most common of all these because it is cost effective and easy to manage. It also will kill off algae and bacteria aggressively, but it also has a downside. The downside of chlorine is that it has a smell that is sometimes uncomfortable when you are smelling it.

Chlorine puts off chloramines when they are added to the water. You will get a strong smell if chlorine when it reacts to the water and when the chlorine levels in the water are too low.

  1. Hot Tub Shock

Hot tub shock is a chemical that will help give a good boost of hot tub sanitizer. This shock can be chlorine shock or non-chlorine shock to help clear your hot tub of algae blooms or cloudy water. If you use a non-chlorine shock for your chlorine or bromine hot tub, you will be able to use your hot tub sooner than if you used a chlorine shock. If you use a chlorine shock, it will take longer to get into the spa, but it will kill off the algae and bacteria better.

For a mineral hot tub, it is best to use a non-chlorine spa shock, keeping your chlorine levels low. For saltwater tubs, it is best to use chlorine shock so that you can get all the algae and bacteria out, but it is okay to use non-chlorine shock, as well.

  1. Alkalinity Increaser, pH Decreaser, and pH Increaser

These chemicals are often the most confusing of all the chemicals that you must use. pH is used to measure how acidic the water is, while alkalinity acts as a buffer to your pH. These two work together and can affect each other with their changes. Your alkalinity level should be around one hundred to one hundred fifty ppm. The best pH level should be around 7.4 to 7.6 because a low pH level can your spa to corrode, while a high pH can lead to burning eyes and dry, itchy skin.

  1. Calcium Hardness Increaser

If the calcium hardness gets too high, you will have to empty the spa and clean it thoroughly. Then you can start over again with fresh, clean water.

  1. Line Flush Cleaner
