What to Look For: Key Features to Consider
When you’re shopping for a starter kit, keep these important things in mind.

3. Brand Reputation
Stick with well-known brands. They usually make good quality products. You can read reviews to see what other people think.
4. Kit Size
Starter kits come in different sizes. Think about how often you’ll use your hot tub. A larger kit might be better if you have lots of swimmers.
What’s Inside? Important Materials Explained
Let’s break down what those bottles and bags do.
- Chlorine (Sodium Dichlor): This is a common sanitizer. It’s fast-acting and easy to use.
- Bromine: This is another great sanitizer. It works well in hot water and is less likely to irritate skin.
- Oxidizers (Potassium Monopersulfate): This “shock” treatment gets rid of body oils, lotions, and other yucky stuff. It makes your water clear again.
- pH Up (Sodium Carbonate): This raises the pH of your water.

Quality Matters: What Makes a Kit Good or Not So Good?
Several things can make a starter kit better or worse.
