How to Shock Your Hot Tub

Does it shock you to learn that shocking your hot tub is a regular and necessary part of water care? Indeed! At Texas Hot Tub Company, we want to help every hot tub owner, new and experienced, to be familiar and knowledgeable with the process. Here is everything you need to know about how to shock your hot tub.

Why Shock Your Hot Tub?

Even with the best spa chemicals and regular water care, bacteria and other contaminants can find their way into your hot tub. Shocking the water regularly will keep it sanitary and safe to use. Additionally, hot tub shock takes effect quickly. You can get your spa chemicals under control and in normal range quickly with a shock.

What is Hot Tub Shock?

Hot tub shock is a concentrated amount of spa chemicals that serves a very important function in your water care. Shock is able to eliminate cloudy spa water, remove organic matter, kill bacteria, and remove chemical byproducts, such as chloramines and bromamines. At Texas Hot Tub Company, our hot tub experts can recommend the best type of hot tub shock for your needs and preferences. 

The Steps to Shock Your Hot Tub

  • Step One: Remove your hot tub cover and store it safely. You will keep the cover off during and after the process so that fresh air is circulating well as you add the hot tub shock. These concentrated spa chemicals need time for off gassing before you put the cover back on.
  • Step Two: Check the spa chemical levels. Your water needs to be balanced in order to make the shock most effective. Test and balance the water as needed before proceeding.
  • Step Three: Turn the circulation pump on. Once you add the shock chemicals, the circulation will help evenly distribute them throughout your spa. However, make sure the hot tub jets are turned off to prevent unnecessary jarring and movement.
  • Step Four: Safety first. Remember that spa chemicals, especially concentrated amounts like shock, should be handled with extreme caution. It is best to wear gloves and goggles when dealing with shock. You should also clean any spills immediately.
  • Step Five: Measure and add the hot tub shock according to the manufacturer’s directions.
  • Step Six: Leave your hot tub uncovered for at least 20 minutes. After that amount of time, you can use your hot tub after testing and balancing the water again.
