Before diving into this article, it’s important to note that every hot tub is different and has unique water care and filtration systems that will determine its specific needs. Bottom line: Always follow the maintenance care instructions in your hot tub owner’s manual to ensure the best care for your specific model.

Hot tub chemical basics

If you’re a beginner, hot tub chemicals may seem daunting or even dangerous. But there is no need to worry. Hot tub chemicals, when used correctly and in accordance with your specific hot tub model, are not intended to harm you. Rather, they are necessary to ensure your water is clear, fresh, and safe to enjoy.

Hot tub chemicals are the agents needed to help prevent bacteria and other microorganisms from developing in your spa water. Without the use of certain chemicals and sanitizing agents, germs can cause your hot tub water to become cloudy or even unsafe to enjoy.

When you are initially choosing a hot tub, asking your hot tub dealer about the unit’s water care and filtration systems is a must. You’ll want to understand from the get-go exactly what will be required of you and what chemicals the spa needs before purchasing it. There are several types of water care systems, and each requires its own unique set of chemicals and other sanitization agents. So exact chemicals, when to add them, and how much, may vary. Here are some common chemicals that many spas use:

Sanitizers—These products, such as chlorine and bromine, are used to kill bacteria in the water. There are many varieties of these agents, from granular chlorine to bromine tablets. There should be an active level of sanitizer in your spa water at all times. Aim for a range of 2.0 to 4.0 ppm (parts per million) of bromine and 1.0 to 3.0 ppm of chlorine.

Balancers—These are used to address the chemistry ranges for pH, alkalinity, and calcium hardness in your spa water. When these three aspects are within their respective ranges, your spa water is balanced. pH reducers, or decreasers, are commonly used to reduce both pH and total alkalinity, which often rise in hot tub water. If you need to raise the levels of both of these, a pH increaser and an alkalinity increaser would be needed.

Shock treatment—This is a concentrated dose of oxidizer and chemicals that destroys organic contaminants such as sweat and body oils. They are quick and fast-acting, often used to kill any bacteria that your usual sanitizers didn’t catch, so to speak. They can also be used to kill algae, bring your spa water back to its beautiful crystal-clear blue color, and even destroy unpleasant odors.

Water clarifier—This will keep your hot tub water sparkling and clear. It can act as a booster for your spa filter or help get your spa water’s clarity back if it starts to get cloudy. If your spa filter is working properly, it usually isn’t necessary to use a clarifier on a regular basis.

Are there alternatives to hot tub chemicals?

Some premium, luxury hot tubs make maintenance easy by way of high-performing water care and filtration systems that require little effort on your part when it comes to adding chemicals or changing filters. There are also various water care systems, all of which require distinct maintenance and chemical use. When you are seeking alternatives to chemical-dependent spas, it is best to speak directly to your authorized hot tub dealer who can help you understand the ins and outs of different water care systems and help guide you to the one that might be best for your needs.

Other supplies to maintain your hot tub

Here are some essentials that can help you preserve your spa water and keep it clear:

A tight-fitting hot tub cover—Many high-end hot tubs come with a cover that forms tightly to the lip of your hot tub. This is a great way to prevent foliage, debris, and dust from getting into your hot tub water and disrupting its delicate chemical balance. If your hot tub does not come with one, a high-quality spa cover is a wise investment.

Cleaners—There are a variety of cleaners to keep your hot tub protected and looking its best. From cleaners for the shell to conditioners for your spa cover, various cleaning agents can help you not only maintain your hot tub but also keep it looking in tip-top shape. It’s important to use cleaners specific for various parts of a hot tub. The only exception is a gentle soap and water, and be sure to give all areas cleaned a very thorough rinse afterward.

Skimmer—A skimming tool makes easy work of scooping debris from your hot tub. After all, hydrotherapy is best enjoyed in a hot tub clear of fallen leaves and other foliage or particles.  

Chemical test kit—There are many types of test kits and strips on the market. The most accurate readings tend to come from liquid drop kits.

Hot tub chemical safety storage tips

If they are used incorrectly or if they fall into the wrong hands (such as little ones), hot tub chemicals can pose a danger. So it is important to, once again, use as directed for your specific spa model, and to keep chemicals out of reach of children and pets.

They should be stored in a cool, dry location between 50 and 80 degrees Fahrenheit. Always make sure caps and lids are on tight and that all chemicals are stored safely to prevent spills and contamination. Avoid mixing chemicals.

When considering what exactly you need for your hot tub chemical starter kit, the best place to start is at your authorized spa dealership. They will know exactly what your chosen spa needs when it comes to chemicals and supplies to ensure you have clear, fresh water that is ready to go when you are. Before you even purchase a spa, they can also guide you to spa brands, such as Sundance® Spas, that feature models with high-performing water systems and filtration systems that make water care easy.
