While trying to buy an alkalinity adjustment chemical, I saw two folks talking about pH, alkalinity, etc. ‘What chemicals do I need for my hot tub?’, one asked the other. I could see the frustration in his face. So, I decided to join the conversation to see if I could take away the frustration from his face. Happily, I did!
The chemicals needed for a hot tub are: sequestering agent/metal remover, sanitizers, alkalinity adjuster, pH adjuster, calcium adjuster, oxidizing shock, and defoamers. If you are wondering the right chemicals you need for your tub, you might want to check the recommendations in this post.
What are hot tub chemicals?
These are hot tub products that should be part of your hot tub regular care. These chemicals serve a different purpose like removing heavy metals from the water, keeping the water clean, or maybe helping to adjust the water pH or its alkalinity.
The different chemicals you need for your hot tub
There are some chemicals that you must incorporate into your hot care routine to help keep your hot tub stable and clean. You wouldn’t want to start having issues after a dip or treating negative effects on your body after a soak. So you need to keep applying some chemicals as part of hot tub water care. The different chemicals you will need are the following:
Sequestering Agent: these will be getting products that will aid in taking off heavy metals or calcium from your water
Sanitizers: you need chemicals that will keep your hot tub balanced and safe for your usage like bromine and chlorine
The Defoamers: these are products that will help take away foamy water from your hot tub. These are foams that came from your body lotions, body oils, and your cosmetics.
Calcium Adjuster: you need products that will help you increase or reduce calcium hardness. It is good to always test the calcium hardness first before use.
pH Adjusting Chemicals: your hot tub will need products that will help in pH increasing and decreasing. Your hot tubs don’t need to be acidic because of the pH level of the water. You need it to be neutral so you can sit conveniently in it. Generally, you need to avoid low or high pH levels because of its side effects. Thus, there is a need for pH adjustment chemicals.
Oxidizing shock: Your hot tubs will also need chemicals like shocking agents to help release oxygen into your water. Shocking the water will help keep your hot tub free from bacteria and chloramines.
