Many new hot tub owners think that a strong chemical smell means there’s too much chlorine in the water. In reality, it often means the opposite. That odor is usually from used-up chlorine that needs to be refreshed with a shock treatment. Misconceptions like this can make water care feel confusing, but it doesn’t have to be. A good starter kit demystifies the entire process by giving you a clear, simple system to follow. This guide will show you how to use your hot tub starter kit chemicals with confidence, sidestepping common mistakes and creating a simple routine for perfect water.
Key Takeaways
- Start with a Complete Kit: A quality starter kit is your best friend, bundling the essentials (sanitizer, balancers, shock, and test strips) to take the guesswork out of your initial setup and weekly care.
- Follow the Chemical Sequence: The order you add chemicals matters. Always adjust total alkalinity first, then pH, then calcium hardness, and add your sanitizer last to ensure each product works effectively and your water stabilizes quickly.
- Test Your Water Regularly: Checking your spa water at least twice a week is the key to proactive maintenance. This simple habit allows you to catch imbalances early and make small, simple corrections before they become bigger issues.
What’s in a Hot Tub Starter Kit?
When you first open a hot tub chemical starter kit, it can feel a little like a high school chemistry class. You’ll see bottles of granules and liquids, test strips, and a guide full of terms you’ve probably never heard before. But don’t worry—it’s much simpler than it looks. Think of this kit as your all-in-one toolkit for creating and maintaining sparkling, safe, and inviting water. Each component has a specific job, and once you understand the role each one plays, you’ll feel confident managing your spa’s water care.
A starter kit is designed to be your friendly introduction to water chemistry, bundling everything you need for the first few weeks of ownership. It takes the guesswork out of buying chemicals individually and gives you a solid foundation for a simple, effective maintenance routine. Instead of wandering the aisles wondering what to buy, you get a curated package that sets you up for success from your very first soak. Let’s break down exactly what you’ll find inside and what each product does for your hot tub.
Sanitizers: The Foundation of Clean Water
The sanitizer is the most important part of your kit. This is usually chlorine or bromine granules, and its job is to keep your water clean and safe by killing bacteria and other microorganisms. Think of it as the guardian of your spa, constantly working to neutralize anything that could make the water cloudy or unhealthy. Consistent sanitization is non-negotiable for a safe soak. A good hot tub starter kit will always include a primary sanitizer to get you started on the right foot, ensuring your water is properly treated from day one.
Balancers: pH and Alkalinity Explained
Next up are the balancers. These products, often labeled “pH Up,” “pH Down,” or “Alkalinity Increaser,” are all about creating harmony in your water. The pH level determines how acidic or basic your water is, and total alkalinity helps stabilize that pH. Keeping these levels in the right range is crucial. If they’re off, the water can irritate your skin and eyes or even cause corrosion on your hot tub’s equipment. Using balancers ensures your sanitizer works effectively and your spa components stay in great shape. If you ever feel unsure, you can always bring a sample to us for a free water analysis.
Shock: What It Is and Why You Need It
“Shocking” your hot tub sounds dramatic, but it’s just a routine deep clean for your water. A shock treatment is a dose of oxidizer that breaks down contaminants like lotions, oils, and sweat that your regular sanitizer can’t handle alone. It also reactivates your sanitizer, giving it a fresh start. Most kits include an oxidizing shock to help you keep the water crystal clear. You’ll typically do this about once a week or after you’ve had a lot of people in the spa to restore that fresh, clean feeling.
Test Strips: Your Water’s Report Card
How do you know if your pH is off or if you need more sanitizer? That’s where test strips come in. These little strips are your water’s report card. You simply dip one in the water, and within seconds, the colored pads will change to show you the current levels of your sanitizer, pH, and alkalinity. Comparing these colors to the chart on the bottle tells you exactly what your water needs. Regular testing is the key to proactive water care, helping you prevent issues like skin irritation or cloudy water before they even start.
Guides and Instructions: Your First Steps
Finally, every good starter kit comes with a user guide. It might be tempting to toss it aside, but this little booklet is your best friend. It provides clear, step-by-step instructions on how to use each product in the kit, how much to add based on your spa’s size, and the correct order for adding chemicals. Many kits even include a waterproof owner’s guide you can keep right by the hot tub. Following these instructions will help you get everything right the first time and build a simple, stress-free routine.
Hot Tub Water Chemistry 101
Think of water chemistry as the foundation of a great hot tub experience. Getting these core levels right ensures your sanitizer works effectively, your water feels comfortable, and your spa equipment stays in top condition. It might sound like a high school science class, but it’s actually pretty straightforward once you know the key players: pH, alkalinity, calcium hardness, and sanitizer. Balancing them in the right order is the secret to crystal-clear water that’s always ready for a relaxing soak.
What is pH and Why Does It Matter?
In simple terms, pH measures how acidic or basic your hot tub water is. The ideal range is between 7.4 and 7.6, which is very close to the pH of human tears. This sweet spot is important for a few key reasons. First, your sanitizer (like chlorine) works most effectively in this range. If the pH is too high or too low, the sanitizer can’t do its job properly, leaving your water vulnerable to bacteria. Second, balanced pH ensures total comfort, preventing the skin and eye irritation that can ruin a good soak. Unbalanced water can also damage your hot tub’s components over time, so keeping it in check protects your investment.
How to Manage Total Alkalinity
Before you even touch your pH, you need to look at the total alkalinity. Think of alkalinity as a buffer that helps stabilize your pH levels, preventing them from swinging wildly up or down. The target range for total alkalinity is between 100 and 120 parts per million (ppm). By adjusting your alkalinity first, you make it much easier to lock in the correct pH level afterward. If your alkalinity is too low, the pH will be erratic and difficult to control. If it’s too high, you’ll struggle to lower the pH and may end up with cloudy water. Getting this level right is the first and most critical step to balanced water.
What is Calcium Hardness?
Calcium hardness refers to the amount of dissolved calcium in your water. You’ll want to keep this level between 150 and 400 ppm. This might seem less critical than pH or alkalinity, but it plays a huge role in protecting the internal parts of your hot tub. If your water is too “soft” (meaning the calcium level is too low), it will try to pull minerals from wherever it can—including the metal, plaster, and acrylic surfaces of your spa. This can cause corrosion and permanent damage. If you’re having trouble, you can always bring a sample to any of our showrooms for a free water analysis.
How Sanitizers Keep Your Water Safe
Sanitizers are the workhorses of your water care routine. Their job is to kill bacteria, viruses, and other contaminants that can thrive in warm water. Chlorine is a popular, effective, and affordable option for keeping your water clean. It’s crucial to maintain a consistent sanitizer level to keep your water safe. A common myth is that a strong chemical smell means there’s too much chlorine. Often, it means the opposite—the chlorine has combined with contaminants and you may need to shock the water. Proper sanitization is essential for every Hot Spring® Spa and is the final step after your other levels are balanced.
How to Use Your Starter Kit
Feeling a little overwhelmed by all those bottles and test strips? Don’t be. Your hot tub starter kit is designed to make water care simple and straightforward. Think of it as your all-in-one toolkit for keeping your spa water clean, safe, and inviting from day one. Getting into a routine is the hardest part, but once you have it down, you’ll find it only takes a few minutes each week. Let’s walk through exactly how to use your kit, from your first fill to your weekly check-ins.
Your First-Time Setup Checklist
When you first fill your hot tub, you’re starting with a blank slate. Your starter kit has everything you need to get the water balanced and ready for your first soak. Inside, you’ll typically find sanitizers, pH adjusters, shock treatments, test strips, and a user guide. The first thing you’ll do is use a test strip to get a baseline reading of your tap water, as its chemistry can vary. From there, follow the instructions in your guide to add the initial chemicals, allowing the jets to run to circulate each one. This first balance is the most important, as it sets the foundation for easy maintenance.
Your Weekly Maintenance Routine
The secret to crystal-clear water is consistency. A few minutes of attention each week is all it takes to prevent issues like cloudy water or algae growth. Your weekly routine is simple: test the water with a strip, read the results, and add small amounts of the appropriate chemicals to bring everything back into the ideal range. That’s it. This simple habit ensures your spa is always clean, safe, and ready for you to enjoy. If you ever feel unsure about your test strip readings, you can always bring a water sample to any of our showrooms for a free water analysis.
How to Store Chemicals Safely
Proper storage is non-negotiable when it comes to spa chemicals. Always keep them in a cool, dry, and well-ventilated place that’s out of direct sunlight. A locked cabinet in a garage or shed is a perfect spot. The most important rule is to store them securely where children and pets cannot access them. It’s also a good practice to keep chemicals in their original, clearly labeled containers to avoid any accidental mix-ups. Wiping down the containers after use will also prevent residue from building up on your shelves and ensure they remain easy to read.
Essential Safety Precautions
Working with spa chemicals is perfectly safe as long as you follow a few basic precautions. First, always wear protective gloves and safety glasses to protect your skin and eyes from splashes. When adding chemicals to the spa, pour them directly into the water—never add water to a container of chemicals, as this can cause a dangerous reaction. Always read the directions on each product label before using it, and be sure to wash your hands thoroughly when you’re finished. These simple habits will ensure your water care routine is always a safe and stress-free part of owning a hot tub.
The Right Order for Adding Chemicals
Believe it or not, the order you add chemicals to your hot tub matters. Following the correct sequence helps each chemical work more effectively and makes the balancing process much smoother. Always wait about 15-20 minutes between adding different chemicals. Here’s the right order to follow:
- Total Alkalinity: Adjust this first. Think of it as the anchor for your pH level. Getting it right makes your pH much more stable and easier to control. Aim for 80–120 ppm.
- pH Level: With alkalinity set, you can now adjust the pH. The ideal range is between 7.2 and 7.8.
- Calcium Hardness: Next, check your calcium levels to protect your spa’s jets, heater, and plumbing from damage. Aim for a range of 150–250 ppm.
- Sanitizer: Your sanitizer (chlorine or bromine) always goes in last. This is what eliminates bacteria and keeps the water safe for soaking. Your target here is 3–5 ppm.
Common Hot Tub Chemical Mistakes (and How to Avoid Them)
Getting your hot tub water just right feels like a huge win, but a few common missteps can quickly turn clear, inviting water into a cloudy, frustrating mess. The good news is that these mistakes are easy to avoid once you know what to look for. Think of water care less as complex chemistry and more as a simple, repeatable recipe for a perfect soak. When you understand the fundamentals, maintaining your spa becomes a quick and stress-free part of your routine, not a chore you dread. By sidestepping these common errors, you’ll spend less time troubleshooting and more time enjoying the wellness benefits of your investment. It’s all about creating a safe, clean, and relaxing environment with confidence. Let’s walk through the four biggest chemical mistakes new hot tub owners make and how you can steer clear of them from day one. This will not only protect your spa’s equipment from premature wear but also ensure the water is always gentle on your skin and safe for everyone to enjoy.
Never Mix Different Chemicals
This is the number one rule of hot tub safety: never mix different chemicals together outside of the tub. Combining them in a bucket or container can cause a dangerous chemical reaction, releasing harmful fumes or even causing a small-scale eruption. The golden rule is to always add chemicals directly to the water, never the other way around. Add one chemical at a time, allowing it to fully dissolve with the jets running before introducing the next one. This simple practice ensures each product works as intended without creating a hazardous situation, keeping both you and your spa safe.
Always Follow the Correct Order
Adding chemicals in the right sequence is crucial for achieving balanced water. If you add them out of order, you’ll find yourself working backward, trying to fix levels that won’t stabilize. Always start by testing and adjusting the Total Alkalinity first, as it acts as a buffer for your pH. Once your alkalinity is in the 80–120 ppm range, you can adjust the pH. After that, check your calcium hardness. Your sanitizer, like chlorine or bromine, should always be the last thing you add. Following this order—Alkalinity, then pH, then Calcium, then Sanitizer—makes the entire process smoother and more effective.
Avoid Over-treating Your Water
When you see that your water is a little off, it’s tempting to dump in a large dose of chemicals to fix it fast. But adding too much can be worse than adding too little. Over-treating can lead to cloudy water, strong chemical odors, and even scaling that can damage your spa’s components. Always start with a smaller dose than you think you need; you can always add more later. If you’re feeling unsure, our Spa Valet Plans offer a perfect hands-off solution, ensuring your water is perfectly maintained by professionals without any guesswork.
Don’t Ignore Your Test Results
Your test strips are your spa’s report card, giving you a clear snapshot of its health. It’s easy to skip a test when the water looks clear, but underlying issues can build up long before they become visible. Make it a habit to test your water a couple of times a week, especially after heavy use. Catching a slight imbalance early is much easier to correct than dealing with a major problem later. If you ever get a reading that leaves you scratching your head, just bring a sample to any of our showrooms for a free water analysis. We’ll help you understand the results and get your water back on track.
How to Choose the Right Starter Kit
Walking down the chemical aisle or browsing online for the first time can feel like a pop quiz you didn’t study for. With so many bottles, brands, and promises, it’s easy to feel overwhelmed. But choosing the right starter kit doesn’t have to be complicated. The goal is to find a single, curated box that contains everything you need for the first few months of water care, taking all the guesswork out of the equation. A good kit provides a solid foundation, giving you the confidence to keep your water clean, safe, and inviting from day one. Think of it as your all-in-one toolkit for creating the perfect spa environment.
Instead of trying to piece together a dozen different products, a starter kit simplifies the process and ensures you don’t miss a critical step. It’s designed specifically for new owners, bundling the essentials into one convenient package. This approach not only saves you time but also prevents the common mistake of buying the wrong type or amount of a certain chemical. By starting with a complete kit, you can focus on learning a simple, effective maintenance routine. This builds good habits from the start and helps you spend more time relaxing in your hot tub and less time worrying about its upkeep.
What Should Be in the Box?
A comprehensive starter kit is your launchpad for easy hot tub maintenance. At a minimum, you should look for a package that includes the core four components. First are the sanitizers, like chlorine or bromine granules, which are essential for killing bacteria and keeping the water safe. Next, you’ll need balancers—specifically pH increaser and decreaser—to keep your water comfortable and prevent equipment damage. The kit must also contain a shock treatment to eliminate contaminants and reactivate your sanitizer. Finally, a set of test strips is non-negotiable, as they are your window into your water’s chemistry. A clear, easy-to-follow guide is the cherry on top.
Balancing Quality and Cost
It can be tempting to grab the cheapest kit on the shelf, but water care is one area where quality truly matters. Premium chemical kits often use more effective, concentrated formulas, which means you may end up using less product over time. More importantly, well-formulated chemicals dissolve properly and are less likely to cause issues like cloudy water, foam, or skin irritation. Investing a little more upfront in a kit with positive consumer reviews for effectiveness can save you a lot of time, money, and frustration down the road. Your goal is to spend more time relaxing in your hot tub, not troubleshooting it.
Finding the Right Kit Size
Hot tub chemical kits aren’t one-size-fits-all. They are typically designed based on the volume of water your spa holds. Before you buy, check your hot tub’s manual to find out its capacity in gallons. A kit designed for a 300-gallon spa won’t last long if you have a 500-gallon model, leaving you scrambling for more supplies. Buying a kit that’s too large isn’t ideal either, as chemicals can lose their potency over time, especially if stored improperly. Choosing a kit that matches your spa’s size ensures you have enough product to get started and establish a routine without waste.
Our Recommended Brands
While you’ll find dozens of brands online, our best advice is to use the water care system recommended for your specific spa.

How to Keep Your Water Perfectly Balanced
Keeping your hot tub water balanced might sound like a chemistry final, but it’s actually a simple routine that protects your investment and ensures every soak is a safe one. Think of it less as a chore and more as a wellness ritual for your spa. Once you get the hang of it, you’ll be able to test and adjust your water in just a few minutes. The key is consistency. Regular testing prevents small issues from becoming big, expensive problems, like damage to your spa’s internal components or skin irritation for your guests. With the right tools and a little know-how, you can maintain crystal-clear, comfortable water all year round. This routine gives you complete control over your spa’s environment, so you can relax knowing the water is perfect every time you step in.
How Often Should You Test Your Water?
To stay ahead of any water issues, you should test your hot tub at least twice a week. If you’re using it frequently or hosting guests, it’s a good idea to test the water before each use. Every person who enters the spa introduces oils, lotions, and other organic materials that can alter the water chemistry. Frequent testing allows you to make small, precise adjustments instead of having to use a large dose of chemicals to fix a bigger problem. A quick check with a test strip only takes a moment and is the single best thing you can do to keep your water clean and inviting.
Signs Your Water is Out of Balance
Your senses are often the first line of defense in spotting unbalanced water. If the water looks cloudy or hazy, that’s a clear sign something is off. Another common indicator is a strong “chlorine” smell. Interestingly, this smell isn’t from too much chlorine, but from waste products called chloramines, which means your sanitizer is working overtime and needs a boost. Unbalanced water can also cause skin or eye irritation. Beyond what you can see and feel, improper chemistry can quietly cause corrosion or scale buildup on your spa’s heating elements and surfaces, leading to costly repairs down the line.
Simple Ways to Adjust Your Water
Adjusting your water chemistry is a straightforward process. After using a test strip to see your levels, you’ll add small amounts of specific products to bring them into the ideal range. If your pH is too high or too low, you’ll use a pH increaser or decreaser. It’s that simple. Another key factor is calcium hardness. If your water is too “soft” (low in calcium), it can corrode your equipment. To fix this, you’ll add a calcium hardness increaser to protect your spa components. Always follow the dosage instructions on the product label for your spa’s size.
When to Add Specific Chemicals
The order in which you add chemicals matters. Adding them in the wrong sequence can cause them to work against each other, giving you inaccurate readings and wasting product. Always start by adjusting the total alkalinity first, as it helps stabilize the pH. Once the alkalinity is in range, adjust the pH. After that, check and adjust the calcium hardness. Your sanitizer (like chlorine or bromine) should always be added last. And remember the golden rule of water care: always add chemicals to the water, never water to the chemicals. This ensures they dissolve safely and properly.
Getting Help When You Need It
Even with a consistent routine, you might run into a water issue you can’t solve. If you’re ever unsure about your test results or how to fix a problem, don’t guess. We’re here to help.

Frequently Asked Questions
Do I really need to use all the different chemicals in my starter kit? Yes, every component in your starter kit plays a distinct and important role. Think of it like baking a cake—you can’t leave out the flour or sugar and expect a good result. Your sanitizer keeps the water safe, the balancers protect your spa’s equipment and keep the water comfortable on your skin, and the shock treatment acts as a weekly deep clean. Using them all in concert is what creates that perfect, crystal-clear water you’re looking for.
How can I tell if my water is unbalanced without using a test strip? Your senses are a great first indicator that something is off. If the water looks cloudy or feels slimy, that’s a clear sign of a problem. You might also notice a strong chemical odor, which surprisingly often means your sanitizer is depleted and needs a boost, not that there’s too much in the water. Finally, if your skin or eyes feel irritated after a soak, your pH is likely out of its ideal range. While these signs are helpful, they only appear after a problem has started, which is why regular testing is the best way to stay ahead of issues.
What’s the single most important step when adding chemicals to my spa? The most critical step is to always balance your total alkalinity first. Think of alkalinity as the foundation that holds your pH steady. If you skip this and go straight to adjusting pH, you’ll find yourself chasing fluctuating levels that never seem to lock in. By getting your alkalinity in the right range first, you make balancing your pH much easier and more effective. This simple habit is the secret to a smooth and stress-free water care routine.
My hot tub has a strong chemical smell. Does that mean I added too much chlorine? It’s a common assumption, but that sharp “chlorine” smell usually means the opposite. The odor comes from chloramines, which are compounds that form when chlorine combines with contaminants like sweat and lotions. When you smell this, it’s a signal that the active sanitizer has been used up and it’s time to shock your water. A shock treatment breaks down the smelly chloramines and frees up your sanitizer to get back to work keeping the water clean.
Is it okay to just buy a generic starter kit online? While it might seem convenient, buying a generic kit can be a gamble. The quality of the chemicals can vary, and you miss out on the expert guidance that ensures you’re getting the right products for your specific spa model. When you purchase a kit from a trusted dealer, you get fresh, high-quality chemicals formulated to work with your spa. More importantly, you get a partner who can answer your questions and even offer services like our free water analysis to help you get things just right.
