What Is A Hot Tub Shock, And What Is It For?

Well, here we come to the most interesting and important point, namely, what hot tub shock treatment is and what is it for. 

Shock for hot tubs is a special chemical additive that is usually used for treating and cleaning water. It quickly and effectively eliminates contaminants, microorganisms, and bacteria that may accumulate in your hot tub.

Hot tub shocks have different chemical compositions, but chlorine and bromine are at the core. These two components are disinfectants that quickly and effectively prevent and destroy the growth of foreign substances in the water. 

As experts, we recommend using a hot tub shock when a regular sanitizer doesn’t do its job well, and you see that the water is poorly cleaned. It’s important to realize that shock is not a replacement for a regular disinfector, and you should still sanitize your water regularly. One of the most important reasons to use this chemical is to boost proper hygiene in the water.

What Are The Criteria For Choosing A Hot Tub Shock?

Well, you and I have already figured out what a hot tub shocking is and why this chemical is needed. Now let’s find out what criteria you need to rely on to choose the perfect product. 

🫙 Disinfectant 

Shock is based on bromine and chlorine. These two components have similar properties, but there are also differences. Chlorine shocks are slightly more effective. Bromine shocks have a cumulative effect and disinfect water better. 

🧪 Product form 

Shock for hot tubs is available in different forms: pellets, tablets, and liquid. It is easier to use the first two, as they are easier to dose. And liquid shock requires a little more effort to measure and add to the water. 

💦 Water Condition 

When choosing a shock for your hot tub, it is important to consider the initial water quality. You can use special test strips to see how many bacteria and microorganisms are in it. If you realize that the water is heavily contaminated, you need to choose a stronger shock (with a higher concentration of the active ingredient). If the water is cleaner, a weaker chemical will work for you. 

👩‍🔬 Safety of use

Read the manufacturer’s instructions for use before purchasing. Also, make sure that you are not allergic to the ingredients in the product. Find out what chemicals are used to treat the pool water — this will help identify potential allergens. You can also observe your symptoms after using the pool. If you experience problems such as itching, rashes, or redness, then you should see a doctor. 

Detailed Reviews

We put a really great deal of effort into selecting these products and analyzed over 100 user reviews and over 50 products for choosing the 4 most worthy ones. For our research we’ve been guided by important criteria and now are ready to show you our winners.

How To Shock A Hot Tub Properly?

So, we learned what a hot tub shocking is, what criteria you should use to choose one, and looked at the 4 best hot tub shocks. Now let’s pay our attention to how to use a hot tub shock correctly step by step. 

Step 1. Check the condition of your water 

Before you use a hot tub shock, you need to understand what the pH and alkalinity levels are. Ideally, the pH is in the 7.2-7.6 range, and the alkalinity is 80-120ppm. You can use special test strips to properly check each indicator. If these values are higher or lower, you need to adjust them correctly, and only then use the hot tub shock. 

Step 2. Clean all the filters in the hot tub 

Make sure they are in good condition and free of dirt. It will help to enhance the shock and distribute all the chemicals properly. 

Step 3. Measure the amount of shock needed 

To do this correctly, carefully read the manufacturer’s instructions, as the dosage may vary depending on the concentration of the product. 

Step 4. Dissolve the shock 

Take a separate container for this. It is important to remember that you should never add the shock just to the hot tub. It can lead to damage and failure of the equipment. 

Step 5. Distribute the shock in the hot tub 

Gently add the mixed shock to the water. Use a special stick to stir and ensure that the shock dissolves evenly. 

Step 6. Give the shock time to work 

This process usually takes several hours. During this time, it is recommended not to turn on the hot tub so that the chemicals have a chance to work properly on the water. 

Step 7. Check the chlorine or bromine level 

If after adding the shock, the chlorine level is not in the 2-4 ppm range and the chlorine level is low, repeat the shock addition process. It is important to realize that if your pool is all bromine based, then you need to check the levels of that particular component.

What Are The Dangers Of Improper Use Of A Hot Tub Shock?

It is very important to properly balance the water in the hot tub with a shock treatment. Otherwise, the following consequences may occur:

  1. Health problems. If the water is not balanced correctly, it can cause irritation, red eyes, and body rashes. Therefore, you should monitor chlorine levels, pH, and other chemical components. 
  1. Improper operation and damage to hot tub equipment. Incorrect use of the shock can corrode the filter, heaters, and other system components. In addition, sediment and sludge can build up on the bottom of the hot tub.
  1. The emergence of bacteria and harmful microorganisms. Improperly balanced water is not safe and will be a catalyst for the growth of bacteria. It can lead to the formation of green deposits and the emergence of an unpleasant odor. 
  1. Reduced hot tub life. If the hot tub water is not properly balanced, it will put a very high strain on the filters. It will cause your hot tub to break more often and cause problems, which will mar your vacation. 

Summary

The hot tub shocking is a very important and indispensable step to achieving clean and safe water. Proper balancing of chemicals is crucial in maintaining optimum conditions for relaxation and recreation in the hot tub. 

But remember, each hot tub has its own water volume and special features, so read the manufacturer’s instructions before beginning to balance the water. The result will be perfectly clean and safe water for your relaxation. 

We have analyzed many important criteria for choosing the right and quality shock. So now your hot tub will be spotless, with clear water.

So I consider it my social mission to share my expertise and educate clients on who is who in the industry. Lately, I started to work with other people who help me to develop the business. In particular, a couple of great researchers and veteran journalists help me convert my raw thoughts into beautiful articles which you might enjoy reading on ByRossi. Hope my efforts help.
