Step 3: Test Your Water

Before you start using your hot tub, it’s essential to test the water to ensure it’s safe and balanced. You can purchase a water testing kit at your local hot tub supply store. Follow the instructions in the kit to test the pH, total alkalinity, and chlorine levels. Adjust the levels as needed until they are within the safe range.

Prime the Pump

• Prime the pump to remove air from the system. Follow the manufacturer’s instructions, which usually involve turning the jets on and off to force air out.

Step 4: Add Chemicals to Your Water

Now that your water is balanced, it’s time to add the necessary chemicals to your hot tub. This will help to keep the water clean, safe, and hygienic. You can purchase hot tub chemicals at your local hot tub supply store. Follow the instructions on the product label when adding the chemicals to your hot tub.

• Test the water using a test strip to determine pH, alkalinity, and sanitizer levels.
• First, adjust the pH and alkalinity. Aim for a pH of 7.4-7.6 and alkalinity between 80-120 ppm.
• Add a sanitizer like chlorine or bromine to kill bacteria. Follow the instructions on the chemical packaging for proper dosing.

Run the Spa

• Turn on the jets and let them run for 15-20 minutes. This helps distribute the chemicals evenly throughout the water.
• Check for leaks around the pump and plumbing connections during this time.

Step 5: Heat Your Hot Tub

Once you’ve added the chemicals to your hot tub, it’s time to heat it. Please turn on the hot tub’s heating system and allow it to reach the desired temperature. It’s essential to wait until the hot tub is thoroughly heated. Depending on the size of your hot tub and the ambient temperature, this can take anywhere from a few hours to a full day.
