How to Use a Hot Tub Chemical Starter Kit

Once you have your kit, follow these steps to keep your water clean and safe:

Step 1: Fill Your Hot Tub with Fresh Water

Before adding any chemicals, make sure your hot tub is clean and filled with fresh water.

Step 2: Test the Water

Use water test strips to check pH, alkalinity, and sanitizer levels.

Step 3: Adjust Alkalinity First

If needed, use an alkalinity increaser to keep levels between 80-120 ppm before adjusting pH.

Step 4: Balance the pH

• If pH is too low, add a pH increaser.

• If pH is too high, add a pH decreaser.

• Ideal pH range: 7.2 - 7.6.

Step 5: Add Sanitizer (Chlorine or Bromine)

• Bromine users: Add tablets to a floating dispenser.

• Chlorine users: Add granules directly to the water.

• Keep levels at 3-5 ppm for safe water.

Step 6: Shock the Water Weekly

Use a shock treatment to remove contaminants and keep water fresh.

Step 7: Maintain Weekly

Test your water twice a week, adjust chemicals as needed, and clean filters regularly.

Common Mistakes When Using a Starter Kit

• Skipping water testing: Always test before adding chemicals.

• Overusing sanitizer: Too much chlorine or bromine can cause skin irritation.

• Ignoring pH balance: Unbalanced water can lead to cloudiness, irritation, or damage to the tub.

• Forgetting to shock the water: Shocking keeps the water fresh and free of buildup.

• Adding too many chemicals at once: Always add one chemical at a time and wait before testing again.

How to Choose the Best Starter Kit for Your Hot Tub

When choosing a hot tub chemical kit, consider:

• Sanitizer Preference: Do you prefer bromine or chlorine?

• Hot Tub Size: Larger hot tubs may require bigger kits or more frequent treatment.

• Ease of Use: If you’re new to hot tub care, choose a kit with clear instructions.

• Extra Protection: Some kits include additional treatments like clarifiers and stain preventers for easier maintenance.

Extra Hot Tub Maintenance Tips

• Drain and refill the water every 3–4 months to keep it fresh.

• Clean your hot tub cover often to prevent mold and mildew.

• Wipe down the hot tub’s surface to remove any buildup.

• Check for leaks and worn-out seals to avoid long-term damage.
