How to Shock a Hot Tub With Bleach

Necessary Items

Before we dive into shocking your hot tub with bleach, let’s ensure you have all the necessary items for this task. Not only does this make it easier to complete, but it also ensures that your hot tub is properly treated and balanced. Here are the items you will need:

  • Chlorine bleach
  • pH testing strips
  • Protective gloves
  • Eye protection
  • Timer
  • Garden hose or water source for filling and diluting bleach

10 Steps on How to Shock a Hot Tub With Bleach

Step 1: Test the Water

The first step in shocking your hot tub is to test the water’s chemical levels. This will help determine how much bleach you must add and if any other chemicals are required to balance the water. Use your pH testing strips to check for the following levels:

  • pH: 7.2 to 7.8
  • Alkalinity: 80 to 120 ppm

If these levels are off, make sure to adjust them before proceeding with shocking the hot tub.

Step 2: Dilute and Add Bleach

Once you have tested the water, it’s time to dilute and add bleach. This step is crucial as adding undiluted bleach can damage the hot tub’s surface. Use your garden hose or a water source to fill a bucket with water and then add 1/2 cup of chlorine bleach per 100 gallons of hot tub water.

To Fill a Bucket

Step 3: Mix Well

After adding the diluted bleach to the hot tub, use your hands or a pool brush to mix it evenly throughout the water. This will ensure that all areas of the hot tub are treated.

Step 4: Run Jets

To help circulate and distribute the bleach even further, turn on the jets for at least 15 minutes.

Step 5: Wait

Now comes the hard part – waiting. Let the bleach sit in the hot tub for at least 30 minutes to an hour, depending on how dirty your water is.

Step 6: Retest Water

After waiting, use your pH testing strips to recheck the chemical levels. If necessary, add more bleach or other chemicals to balance the water.

Step 7: Wait Again

Yes, more waiting. It’s crucial to wait at least 30 minutes after adding any other chemicals before proceeding with the next step. To ensure the proper distribution of chemicals, be patient.

Step 8: Run Jets Again

Turn on the jets once more to help circulate and mix the chemicals throughout the water. Patience is critical when it comes to shocking a hot tub. Let the chemicals sit and work their magic for another 30 minutes to an hour.

Step 9: Drain and Refill the Hot Tub

After running the jets, drain the hot tub completely and refill it with fresh water. This will help remove any excess chemicals.

Step 10: Test and Enjoy

Once the hot tub is refilled, use pH testing strips to ensure all levels are within the recommended range. Once confirmed, your hot tub is now ready for you to enjoy!

Following these ten simple steps on how to shock a hot tub with bleach, you can ensure that your hot tub water remains clean and balanced. Remember always to test the water before and after shocking, be patient, and use caution when handling bleach. With this knowledge, you can enjoy crystal-clear spa water whenever you want!

8 Tips and Precautions

Set a timer for the recommended waiting times to ensure that chemicals have enough time to circulate and work properly.
