Step 4: Applying the Shock Treatment

Applying shock treatment to your hot tub is essential to hot tub maintenance. Shocking the hot tub helps to keep the water clean and safe by removing organic contaminants, bacteria, and other impurities. Here’s a step-by-step guide on how to apply shock treatment to your hot tub:

Materials You’ll Need:

  1. Hot tub shock treatment chemicals (chlorine-based or non-chlorine shock)
  2. Protective gloves and eyewear
  3. Measuring cup or scoop
  4. Bucket or container
  5. Stirring stick or brush
  6. Hot tub test strips or a water testing kit
  7. Spa filter cleaner (optional)

Steps:

Safety Precautions: Put on protective gloves and eyewear to ensure your safety while handling chemicals.

Test the Water: Use hot tub test strips or a water testing kit to check the current water chemistry. This includes testing for pH, chlorine or bromine levels, alkalinity, and calcium hardness. You need to know the current state of your water to determine the appropriate amount of shock treatment to add.

Calculate the Shock Treatment Dosage: Follow the instructions on the shock treatment product’s label to determine the proper dosage based on your hot tub’s size and the current water chemistry. Use a measuring cup or scoop to accurately measure the shock treatment chemical.

Dissolve the Shock Treatment: Fill a clean bucket or receptacle with warm water. Then, slowly add the measured shock treatment chemical to the water while stirring. This helps to dissolve the shock treatment evenly and prevents it from settling at the bottom of the hot tub.

Apply the Shock Treatment: Turn off the hot tub’s circulation system to prevent the shock treatment from being immediately dispersed. Pour the dissolved shock treatment solution evenly around the edges of the hot tub. Avoid adding it all in one spot to prevent localized high concentrations.

Circulate and Wait: Turn the hot tub’s circulation system back on and let it run for at least 15-30 minutes. This allows the shock treatment to thoroughly mix with the water.

Retest the Water: After the waiting period, retest the water with your testing kit. The shock treatment may have affected the water chemistry, so ensure that the pH, chlorine, or bromine levels and other parameters are within the recommended ranges.

Wait Before Using: Depending on the shock treatment product used, you may need to wait a specific amount (usually several hours) before using the hot tub again. Refer to the product’s instructions for guidance.

Optional: Clean the Spa Filter: If your hot tub has a filter, consider cleaning or replacing it as part of your regular maintenance routine. A clean filter helps maintain water quality.

Regular Maintenance: Establish a regular maintenance schedule to keep your hot tub water clean and safe, including testing the water, adjusting chemicals as needed, and cleaning the hot tub filter.

Always follow the manufacturer’s instructions on the shock treatment product and consult your hot tub’s manual for specific water chemistry and maintenance guidance. Adequately maintained water will ensure your hot tub remains a relaxing and enjoyable experience.
