Best Hot Tub Chlorine: Top 10 Options
Published on
Finding the best hot tub chlorine is key to a clean and safe hot tub experience. Chlorine keeps your tub free of germs and algae.
But with so many options out there, how do you choose?
This guide will help you understand what makes a chlorine product stand out. Dive in to discover your best choice for a sparkling, inviting hot tub.
What Is Hot Tub Chlorine?
Hot tub chlorine is a special cleaner for your hot tub. It's a chemical that kills germs and bacteria. When you put it in the water, it works immediately.
This full salt system keeps the hot tub water clean and safe for you to enjoy. Think of it as a tiny, invisible cleaning crew for your hot tub.
The Science Behind Chlorine in Hot Tubs
Think of chlorine as a tiny army. When you drop it into the water, it starts to break apart. This split creates new parts called "chlorine ions." These ions love to fight germs and bacteria.
The chlorine ions attack and destroy 99% of the germs in your hot tub. This keeps your hot tub clean and safe for you to enjoy.
But the chlorine doesn't stop there. It continues to guard your hot tub, always ready for the next batch of germs. It only stops when it's used up and there's none left.
That's why you need to add more chlorine from time to time. This keeps your chlorine army strong and ready to keep your hot tub clean.
Remember, too little chlorine, and germs could take over. Too much, and it might irritate your skin or eyes. You want to keep the right amount for a happy, healthy hot tub experience.
Possibility and Implications of a Chlorine-Free Hot Tub
Can you have a hot tub without chlorine? Yes, you can. But is it a good idea? Let's think about that.
Having a chlorine-free hot tub might sound appealing. No chemical smell, cloudy water, and less skin irritation. But you can't forget about cleanliness.
Chlorine kills bacteria. Without it, your hot tub could turn into a giant petri dish. You wouldn't want to relax in a germ soup.
There are alternatives to chlorine, like both chlorine and bromine, ozone, or saltwater spa systems. These can kill bacteria too. But they may not be as effective as chlorine. Plus, they come with their own downsides.

- Chlorinating granules
- Chlorine tablets
- Chlorine concentrate
- Chlorine shock
- Liquid chlorine
- Dichlor chlorine
- Trichlor chlorine
- Sodium hypochlorite

This table lists the key aspects about them.
1. Chlorinating Granules
Chlorinating granules are a type of pool and hot tub disinfectant. They are small, concentrated grains of chlorine that you add to your hot tub water to kill bacteria and other germs.
When these granules come into the water, they dissolve fast. It's like adding a team of tiny cleaners to your hot tub to keep it fresh and safe for your relaxation.
How to Use Chlorinating Granules
Using chlorinating granules is quite easy:
- Measure the right amount based on your hot tub's size. You can usually find this information on the product's label.

Benefits of Chlorinating Granules
Chlorinating granules have several benefits:
- They dissolve fast, which means they start working right away.
- They're also easy to measure, so you can adjust the amount to suit your needs.
- Because they're concentrated, a small amount can go a long way.
Downsides of Chlorinating Granules

- Because they dissolve fast, you may need to add them more often to keep your hot tub clean.
Who Should Use Them
Chlorinating granules are great if you use your hot tub often. They're also a good choice if you need to boost the chlorine level fast.
If you're comfortable adjusting the amount you use based on your hot tub's needs, chlorinating granules can be a good fit for you.
2. Chlorine Tablets
Chlorine tablets are a type of pool and hot tub sanitizer used to keep the water clean. They're solid tablets made of a compound called trichloro-s-triazinetrione. This is a stable source of chlorine.
Think of chlorine tablets as a slow-release cleaning agent. Once in the water, they do their job, so you can relax and enjoy your hot tub without worry.
But remember, it's still important to regularly check your hot tub's both chlorine levels and pH levels to keep the water balanced.
How to Use Them
Using chlorinating tablets for your hot tub is simple:
- Make sure your hot tub is filled with water.
- Put the tablets in a floating dispenser or your tub's chemical feeder.
- Don't put the tablets directly into the tub. This can bleach your tub's lining.

They're easy to use. You don't have to measure out the amount like with granules. They're also compact and easy to store.
Downsides
But there are downsides too. Over time, these tablets can lower your tub's pH. This can make the water acidic, which isn't good for your tub or your skin.
Also, they don't work as quickly as some other types of chlorine. If you need a quick fix, tablets might not be your best option.
Who Should Use Them
If you use your hot tub often, chlorinating tablets could be a great choice. They give a steady supply of chlorine, which means you don't have to add more every day.
Remember to keep an eye on your water's pH.
3. Chlorine Concentrate

This means a single bottle can last a hot tub owner a long time. It's also quick to work, helping to keep your outdoor hot tub both clean and safe.
Downsides
Despite its strengths, chlorine concentrate can be harsh on the skin and eyes if you don't use it correctly.
Who Should Use It
If you're someone who uses your hot tub often, chlorine concentrate could be a good fit.
It helps keep the water clean. But remember, you should always handle it with care to avoid any irritation.

It's a key part of keeping your hot tub clean and safe.
5. Liquid Chlorine

Also, it's heavier and more cumbersome to carry than other types of chlorine.
Who Should Use Liquid Chlorine
If you use your hot tub often, liquid chlorine could be a good choice. It's also helpful if you need to sanitize your hot tub quickly.
It's like having a speed-cleaning service for your hot tub. But if carrying heavy jugs or storing big containers is a problem, you might want to consider other options.

It works by killing bacteria, algae, and other microorganisms that can make the water unsafe or unpleasant to use. Think of Trichlor as a very tough cleaner that fights off the tiny, unwanted guests in your hot tub.

How To Choose Hot Tub Chlorine for Hot Tub Water
Choosing hot tub chlorine depends on factors like your tub's size and usage frequency. A larger hot tub shell, or more frequent use of a hot tub requires more chlorine to maintain a clean and safe water environment.
Getting the Best Value for Your Money
Look for high-quality products that provide excellent sanitizing power and long-lasting effect. Cheaper options might require more frequent application, which could eventually cost more in the long run.
Catering to Your Specific Needs
Consider your skin sensitivity and the preferences of those using the hot tub.
Some people are more sensitive to certain types of chlorine. For instance, Dichlor is often recommended for people with sensitive skin as it has a nearly neutral pH and dissolves rapidly.
Making an Informed Purchase Decision
Researching and reading reviews can be beneficial. Understanding the experiences of other users can help guide your decision.
Tablets often have slower dissolution rates, making them a great option for long-term maintenance. Granules or shocks work rapidly and are best used for immediate sanitizing needs.
It's crucial that many hot tub and spa owners have to strike a balance between efficiency, cost-effectiveness, and comfort for the best hot tub experience.
