Congratulations on your new hot tub! That excitement you're feeling right now? It's about to get even better once you understand the magic happening behind the scenes with your water care.
Think of your starter kit as your hot tub's medicine cabinet—each product has a specific job that keeps your water sparkling and your soaks absolutely perfect. No guesswork, no confusion, just everything you need to become a hot tub hero (cape not included, but bubbles definitely are).
The Foundation: Your Sanitization Squad
Let's start with the heavy hitters—the products that keep your water clean and safe for everyone who takes a dip.
Chlorine Granules are your primary sanitizer—think of them as your water's security team. They eliminate bacteria, viruses, and other nasties that could crash your hot tub party. Unlike pool chlorine, spa chlorine granules dissolve quickly in hot water and won't leave you waiting around.
The beauty of granules over tablets? Complete control. You add exactly what you need, when you need it, without worrying about over-chlorination from slow-dissolving tablets that keep working whether you want them to or not.
Chlorine Test Strips are your early warning system. These little strips tell you four crucial things: free chlorine levels, pH, total alkalinity, and stabilizer levels. Dip, wait fifteen seconds, and compare to the color chart on the bottle. Simple as that.
Testing isn't just busy work—it's how you catch problems before they become expensive headaches. Trust me, spending thirty seconds with a test strip beats spending three hours trying to clear up cloudy water.
Pro Tip: Test your water at least twice weekly, but always test before adding any chemicals. Your hot tub's chemistry changes based on usage, weather, and even what lotions people wear into the spa. Regular testing keeps you ahead of the curve.
Spa Shock is your water's reset button. This non-chlorine oxidizer breaks down the stuff that chlorine can't handle alone—body oils, lotions, cosmetics, and other organic contaminants that make water cloudy or cause that "chlorine smell" (which is actually the smell of chlorine working overtime).
Think of shock as your cleanup crew. After each soak, add half a capful per person who used the tub. It frees up your chlorine to focus on sanitizing instead of dealing with the aftermath of your relaxation session.
The Balancing Act: pH and Alkalinity Masters
Water balance isn't just chemistry class flashbacks—it's what makes the difference between a luxurious soak and an uncomfortable experience.
pH Down lowers both pH and alkalinity when your water tests high. High pH makes chlorine lazy (seriously, it becomes much less effective), can cause scale buildup on your spa shell, and might leave your skin feeling dry or itchy.
Alka Up raises alkalinity levels, which acts like a buffer for your pH. Proper alkalinity prevents your pH from bouncing around like a pinball. When alkalinity is in the sweet spot (100-120 ppm), your pH stays stable, and everything else falls into place.
Here's the thing about these two: they work together like dance partners. Sometimes you need to adjust alkalinity first, then pH. Other times, pH Down handles both jobs at once. Your test strips will guide you, but remember—no more than three capfuls in a twenty-minute period. Patience pays off in water care.
Pro Tip: Always run your pumps on high speed when adding any chemicals, and keep the cover open for at least 20 minutes. This ensures proper mixing and prevents chemical concentration in one area of your spa.
The Comfort Crew: Making Water Feel Amazing
Clean water is great, but water that feels silky and luxurious? That's what transforms a basic soak into a spa experience.
Ultra Spa Conditioner is like a multivitamin for your water. It softens hard water, helps clarify cloudiness, and gives your water that silky feel that makes you want to stay in just a little longer. The secret ingredient? Borates, which help stabilize pH and make your sanitizer work more efficiently.
Add six capfuls during initial setup, then two capfuls weekly. Your skin will thank you, and you'll notice the difference immediately. Water conditioned with Ultra Spa feels softer and leaves you feeling refreshed rather than dried out.
Stain & Scale is your insurance policy against mineral buildup. If your area has hard water (and most places do), dissolved minerals like calcium, iron, and copper can cause staining on your spa shell and scale buildup in your plumbing.
This product binds those minerals, keeping them suspended in the water where your filter can catch them instead of letting them stick to your spa surfaces. Use 60ml per 1000 liters during setup, then 30ml weekly. It's way easier than trying to remove stains later.
Zorbie might look like a simple sponge, but it's actually a sophisticated oil-absorption system. This floating companion captures body oils, lotions, and other organics before they can cause foam or that ring around your waterline.
Just drop it in near your filter—don't squeeze it first—and let it do its thing. When it starts sinking about halfway down, it's time for a replacement. Most people get 1-3 months out of each Zorbie, depending on usage.
The Game Changers: Advanced Water Care
These last two products take your water care from good to exceptional.
Spa Solution is pure magic in a bottle. This enzyme-based water conditioner is 100% natural and does three incredible things: reduces skin and eye irritation, cuts down on the amount of chemicals you need, and gives your water an unbelievably smooth, silky feel.
Pour the entire bottle into your spa every time you drain and refill (every 3-4 months). The enzymes work continuously to break down organic contaminants, which means your sanitizer can focus on what it does best—keeping water safe.
Nature2 Mineral Sanitizer adds a whole new dimension to your water care. This mineral cartridge releases silver and copper ions that provide an additional layer of sanitization. It's like having a backup security system for your water.
Slide it into your primary filter housing (the one with the grate), and it works for four full months. The best part? It reduces the amount of chlorine you need while making your water feel softer and more natural.
Pro Tip: With Nature2 in place, you can maintain chlorine at just 1-3 ppm instead of the usual 3-5 ppm. Your skin will feel the difference, and you'll use fewer chemicals overall.
Putting It All Together: Your Water Care Strategy
Now that you know what each product does, here's how they work as a team:
During Initial Setup:
- Test strips guide your balancing efforts with pH Down and Alka Up
- Chlorine provides primary sanitization
- Spa Shock clears out any initial contaminants
- Ultra Spa conditions the water for comfort
- Stain & Scale prevents mineral problems before they start
- Spa Solution creates that luxurious feel
- Nature2 goes into your filter for ongoing mineral sanitization
- Zorbie starts capturing oils immediately
For Ongoing Maintenance:
Your test strips become your best friend, guiding weekly adjustments with pH Down, Alka Up, and chlorine. Spa Shock handles post-soak cleanup, while Ultra Spa and Stain & Scale keep water feeling and looking great weekly.
Every few months when you drain and refill, you'll replace your Spa Solution and Nature2 cartridge, and probably need a fresh Zorbie too.
Why This Combination Works
You might wonder why we chose these specific products for your starter kit. It's not random—each item addresses a common challenge new spa owners face:
Water balance issues? pH Down and Alka Up have you covered, with test strips to guide you.
Sanitization concerns? Chlorine handles primary sanitization, while Nature2 provides backup and Spa Shock deals with contaminants.
Comfort problems? Ultra Spa softens water, Spa Solution adds that silky feel, and Zorbie prevents foam and oils.
Mineral buildup fears? Stain & Scale keeps hard water from causing expensive problems.
This isn't just a collection of chemicals—it's a complete water care system designed to work together seamlessly. Each product makes the others more effective, creating water that's not just clean and safe, but genuinely enjoyable.

Frequently Asked Questions
How long will my starter kit last?
Most products in your starter kit will last 2-4 months with normal use. Chlorine and Spa Shock typically run out first since they're used most frequently. The Nature2 cartridge lasts exactly 4 months, while Zorbie replacement depends on usage—usually 1-3 months.
Can I use different brands with my starter kit products?
While you can mix brands, we recommend sticking with the same product line when possible. These products are formulated to work together, and mixing different brands can sometimes cause unexpected reactions or reduce effectiveness.
What if my test strips show everything is perfect but my water still looks cloudy?
Cloudiness often indicates your filter needs cleaning or your sanitizer levels were too low recently. Try cleaning your filters with a Filter Flosser, shocking the water, and running pumps continuously until it clears.
How do I know when to replace my Nature2 cartridge?
Mark your calendar for exactly 4 months from installation. The minerals don't run out gradually—they stop working effectively right around the 4-month mark. Many people set a phone reminder when they install it.
Is it normal for my water to foam a little at first?
Some initial foam is normal, especially if residues from manufacturing or cleaning are present. Your Zorbie will help eliminate this quickly. Persistent foam usually indicates oils from lotions, soaps, or detergent residue on swimwear.
