How Much Chlorine Granules to Shock Hot Tub Effectively

Every owner has to provide cleanliness, safety, and invitation inside their tub. The shock of hot tub water with a rational frequency is an effective solution to keep your hot tub clean and safe for relaxing or taking a bath in it. This water treatment method can undoubtedly remove the bad bacteria, organic substance, and other things that may do harm to the water quality in any hot tubs.

Introduction

Chlorine granules are one of the most advanced types of disinfectant and sanitizer used for shocking a hot tub. But how much chlorine granules to shock hot tub for a spa aim effectively? This post will show almost everything you need to know to maintain a pure, clean and no-bacteria water circulating in a hot tub with chlorine granules.

What Hot Tub Shock Means?

As a sanitizing process, hot tub shock is the dosage of oxidizing chemical materials like chlorine granules or tablets added to the spa hot tub water for purification. These chemicals break down organic material that steadily builds up and isn’t removed by routine sanitizers such as chlorine or bromine. Examples of organic material include oils from various lotions, makeup, sunscreen, dead skin cells, and even bacteria in your spa’s warm, moist environment.

The following reasons may urge you to shock your spa hot tubs.

Organic Contaminant Removal: Oils, lotions, and many products on the body accumulate in water over time. Shocking breaks these organic materials down, thus allowing one to have clear water that is free from scum in the hot tub.

Kill Bacteria and Unwanted Microorganisms: In fact, hot tubs are ideal places for pathogenic bacteria or microorganisms to survive. As timely sanitization can keep bacteria in check from time to time, shocking with chlorine or non-chlorine method ensures that any bacteria of algaes can be completely eliminated.

Resolve Chloramines: When chlorine meets organic substances, chloramines come. These are responsible for the powerful scent of chlorine associated with pools and hot tubs. Water shock breaks down chloramines and restores chlorine to its influential position as a sanitizer.

Why Chlorine Granules?

Chlorine granules-very often seen in a dry, powdered form of chlorine used in hot tub shocking-can dissolve into the water quickly once inserted into the spa and release chlorine to sanitize or oxidize contaminants rapidly.

Compared to liquid chlorine or even types of chlorine in tablet forms(i.e. chlorine tablet), granular chlorine remains a popular companion for hot tub owners because it is easy and quick to dissolve in water. There are a few significant benefits related to chlorine granules:

Fast Dissolving: Granular chlorine dissolves quickly in water; it will start affecting water cleanliness immediately.
Stability: Chlorine granules are stabilized to work effectively even at higher temperatures, which should suit your hot tub.
Precision: Granules allow proper and more accurate dosing to treat your hot tub correspondingly.

How Much Chlorine Granules To Shock Hot Tub Effectively?

As what we mentioned above, how much chlorine granules to shock hot tub usually depends on its size, the water quality status, and utilizing frequency. Dosing 1 or 2 teaspoons of chlorine granules per 100 gallons of water in a hot tub is a standard shocking rule for you to follow, which should be the inital quantity for regular shocking treatment.

Adjust for Hot Tub Size: If your tub holds 300 gallons of water, you could use approximately 3-6 teaspoons of chlorine granules. If your hot tub holds 500 gallons, you will use 5-10 teaspoons.
Water Clarity and Frequency of Use: the murkier the water or the more the hot tub is used, the more chlorine granules will be required. Add more if you have been shocked for a while.

It is worth noting, however, that although this may be the general rule, it is always prudent to refer to the manufacturer’s instructions about the chlorine granules and your hot tub, given that some chlorine brands may sometimes have varying specifications due to chlorine concentration.

4 Steps to Shock A Hot Tub With Chlorine Granules

Shocking a hot tub is relatively easy to do with chlorine granules. Here is a step-by-step process:

1. Preparation

Remove the hot tub cover and leave it that way during shock. The shock will turn off the gas.

Moreover, a spa hot tub’s ideal pH level should be between 7.4 and 7.6. You do need to adjust in accordance with either a pH level’s increase or decrease before handling the shock with chlorine granules or chorine tablets.

2. Measure the Correct Quantity of Chlorine Granules

Using your measured hot tub volume, measure chlorine granules using a measuring cup. Consider 1 to 2 teaspoons per 100 gallons.

3. Chlorine Granules Addition

Add the chlorine granules slowly and directly to the water. To ensure proper dissolution, perform this function at the deep end of the tub. Do not sprinkle granules into the water, which may lead to inappropriate dissolution.

4. Circulate the Water

First, turn the circulation pump on and allow the jets to run in the hot tub. This circulates chlorine granules through the water. Allow the water to circulate for at least 20-30 minutes to ensure it spreads everywhere.

After shocking, check the water’s chlorine level; it must read in the ideal range of 1-3 ppm. If it’s higher than that, wait until the reading drops before getting in the hot tub.

Mistakes You May Make During the Course of Shocking a Hot Tub

Shock treatment is necessary for your hot tub; however, only some people tend to make mistakes. Following are a few of the most common mistakes one should avoid:

Adding Too Much Chlorine: Adding too much chlorine into the pool to increase the levels of active sanitizers makes it unsafe for use. No more chlorine should be used than recommended by dosage.
Failure to Test pH: Chlorine does not act if the pH is too high or too low. Always test for pH and adjust before shocking. If the water temperature is below the required temperature, chlorine will not dissolve and can act with lower efficiency. The best results are obtained if the water temperature is above 60°F —15°C.
Not Circulating the Water: If properly circulated, the chlorine granules may disperse evenly and leave most of your hot tub parts unexposed.

How Often Should You Shock Your Hot Tub?

This depends on many factors, including, but not limited to, the quantity of use, the quality of water inside the tub, and environmental concerns surrounding it. A general rule of thumb would look something like this:

Shock Weekly/Bi-Weekly: If you use your hot tub pretty frequently, it’s a good idea to shock it every week or so, every other week.
More People in the Hot Tub or Use: The more your hot tub is used, the more frequently the shocking process will occur.
After Rain or Storms: Rain and storms stir up debris and contaminants into the water, thus requiring more frequent shocking.

3 Tips on Keeping Your Hot Tub Water Clean

Clean Filters With a Proper Frequency: Filtration in water circulation and quality is definitely essential, therefore, clean or replace them as per the directions and instructions from the very supplier.
Use a Cover to Protect Your Tub: A cover for protecting your hot tub is absolutely a must-have thing in order to keep the water away from debris during the period of not using it.
Water Chemistry Inspection: Timely test the pH data, alkalinity, and sanitizer levels regularly and adjust to achieve a healthy balance of the above parameters in the water.

Conclusion

The shock composition of chlorine granules makes keeping the water in your hot tub clean, clear, and safe easy and efficient. When dosed correctly and the water chemistry is appropriately maintained, the hot tub will continue in good condition after each soak. Regular shocks with proper maintenance are also crucial for a pleasant and hygienic spa experience.
