Do You Need To Shock An Ozone Pool?

An ozone pool is a pool that uses ozone gas instead of chlorine or bromine to kill bacteria and other microorganisms. The two main benefits are the elimination of odour and skin irritation in the water.

An ozone treatment lasts approximately four hours, while a chlorination treatment can last up to eight hours.

No! To avoid potentially triggering other people or injuring yourself, avoid shocking an ozone pool.The main reason for this is that there is no filter system in the ozone pool.This means you need to take extra precautionary measures to not touch the water with your bare skin or clothing.

If you’re unsure whether you’ve shocked an ozone pool or not, contact your local professional before wasting any effort trying to clear it out yourself.

As a general rule of thumb, the following steps should be taken to clear a clogged ozone pool system.

First, turn off your oxygen system (if applicable). This will prevent the ozone generator from pumping any ozone into the swimming pool.

Next, unplug your ozone generator and all of the cords or hoses connected to it. This will prevent any further current from being produced even if there is still water in the pool or debris in the generator itself.

Attach a hose to the return port at the bottom of your ozone pool. This will allow you to drain the remaining water from the pool.

After removing the water from your pool, you can disconnect your ozone generator from where it’s plugged into an outlet and clean it inside and out.

Using a brush, scrub the inside of your generator for any debris that could have built up within it.

Ensure that you hose down your ozone generator outside to remove any debris from the exterior of it. Also, ensure you do not get water into the ozone generator’s control box or electrical components.

Once the outside of your ozone generator is immaculate, plug it back into an outlet and turn on your oxygen system (if applicable).

Now drain the water from your swimming pool, and you can clean out the bottom of your pool and any other steps that may need to be taken.

This is a basic overview of how to avoid shocking an ozone pool and what actions you should take to ensure it stays free from debris.

Do You Need Chlorine With A Pool Ozonator?

Yes! Your pool needs chlorine to quickly break down organic contaminants and green slime, especially if you have a saltwater pool.

The key is that the chlorine has to be fast acting, meaning it could only break down what’s in your water and not bind with any other materials such as the metal in your pool.

Which would then keep those contaminants from being broken down and reintroduced into your body. Ozone can also kill parasites like giardia.

Do You Need To Shock An Ozone Pool?

Chlorine is not such a good oxidizer. It’s more reactive than ozone, which can lead to chlorine gas forming that irritates the skin (eyes and nose) and lungs.

Add an extra dose of chlorine in pools with much organic material in the water like dirt, algae, or Slime Mold.

Ozonators are a better alternative to chlorine. They don’t generate acidic gas like chlorine. They boast more effectiveness in waste treatment and do not impact PH.

Also, they don’t produce any chloramines (which are carcinogenic when breathed in). Ozone in water forms an alkaline PH because ozone has a higher oxidation potential at alkaline pH levels (it has a stronger capacity for disinfection).

Note that you can’t leave the ozone generator on 24 hours a day for fear of running out of ozone. Maybe you have been told that ozone generators are like adding chlorine to your pool, and the “shock” will put your pool back in balance.

You need to remove the minerals in your water and treat it with ozone. Ozone will not oxidize them; you must remove them using filtered solid water first, or they won’t go away even after heavily shocking your pool with chlorine.

How Do You Maintain An Ozone Pool?

Ozone pools are designed to kill bacteria, contaminants, and other nasties to give you the cleanest and healthiest water possible.

Here is how you maintain an ozone pool:

Make sure your equipment is working correctly and using suitable filters.

Run your pool often, removing any debris or dirt that has settled on the bottom.

You can either run your pool as usual or vacuum it daily to ensure there is no buildup on the bottom of the pool, which could lead to contamination or other issues with less frequent water changes and filter cleaning.

Always test your pool water. For sanitizer levels, you should check water chemistry and pH frequently.

In the winter, keep your pool covered to maintain a friendly and warm environment for your fish and other animals to enjoy.

Maintain your chemicals and anti-bacterial treatment. If they are not being used regularly, you will need to replenish them, as the treatments can lose effectiveness over time.

If you are not using your pool this summer, keep it open and take advantage of the great benefits that an ozone pool has to offer.

Enjoy the water filters and natural sanitizers regularly, and use safe bleach/water treatment when necessary.

Make sure to keep your pool equipment in good working order and that you have everything scheduled to maintain your pool.

Be aware of any warning signs and know what to do when your pool is contaminated to keep it clean and healthy.

Can You Shock An Ozone Pool?

Yes! I recommend you shock your ozone pool to supplement most ozone systems. Check the product information before using it. As with any chlorine or bromine-based system, there are times when an ozone shock is necessary for optimum performance.

Ozone works by absorbing chlorine and bromine. That is, it converts them into oxygen and ozone.

Ozonation is a chemical reaction that occurs when a chemical compound such as chlorine or bromine is exposed to an electron-rich plasma, such as natural spring water.

The process of converting the chemicals into ozone is called oxidation.

You can only use chlorine once. If it’s not converted during regular operation, the water will turn green and far too dirty for swimming. Hence it would be best if you shocked the pool at least 2-3 times a week.

Since you are dealing with minerals (which help reduce the amount of chlorine needed) and a ” shockable ” system, you must be careful when shocking your pool.

Shock levels can be determined by:

  • Amount of use
  • Regularity of shock
  • Soil conditions

If your area boasts hard water and your water’s pH tends to rise above or below 7, chlorinating regularly could mean that it will be necessary to raise or lower the pH before you shock.

Why Is My Ozone Pool Cloudy?

Your ozone pool is cloudy because it boasts a broken or faulty part; this might be due to heat damage, poor installation, outside contamination, or an off-gassing chemical.

However, the beginning of the cloudy appearance is the same for all of these problems. The average pool has anywhere from 3-6 inches of water at night when it is closed and covered with a tarp.

This water is constantly trying to cool the water and any contaminants.

This causes agitation that leaves a film that causes your pool to “cloud up” whenever it has been open long enough, generally 2-3 weeks, for a bit of water to evaporate and leave a film behind.

In addition, this motion from the shade and turbulence from wind can stir up any remaining contaminants in your pool to leave another film behind.

This is a problem that every pool builder struggles with when they are designing a new pool.

The best way to ensure that your new pool has clear, cloud-free water is to design it with no circulation or use the most appropriate circulation system to do the job.

You can also have a closed-loop recirculation system with a pump precisely the right size for the job.

Every pool’s circulation system should have an automatic safety feature that shuts the pump off after 24 hours to prevent over-stressing your pump.

This area of circulation design can be very tricky as every pool is different, and there is no “one size fits all” answer.

Does Ozone Replace Chlorine?

Yes! You can replace chlorine with Ozone (O3) as a disinfectant for your hot tub.

In most cases, you can save on the cost of bleach and other chemicals and reduce the potential for harmful conditions such as hydrogen sulfide (H2S) or even sulphur dioxide (SO2).

It is also environmentally friendly, considered safer, and has minimal impact on some aquatic life.

Ozone and chlorine work in different ways. Chlorine is a powerful oxidizer and kills bacteria by destroying their DNA, enzymes, and proteins.

Chlorine is used to disinfect swimming pools or hot tubs with a large surface area where the water continuously circulates.

Ozone has a small molecular weight and acts as an oxidizer on an atomic level, destroying all types of organic matter. This includes algae, bacterial spores, and viruses.

Although most ozone generators are based on ozonated sodium chloride, commonly referred to as “ozone generator salt,” or other ionized products from an electrolyzer.

Some manufacturers still use various formulations varying from metal halides to molecular oxidation.

Ozone is a hazardous gas and cannot be created or stored for long periods. A premixed batch of ozone is destroyed in just days by sunlight, heat, and high humidity.

Furthermore, the shorter life span of ozone makes it more difficult to control.

In comparison, you can recycle chlorine as a bleaching agent for clothes making it easier to control and safer because it requires less frequent additions.

Does Ozonator Run All The Time?

No! Your Ozonator should run at least 4-6 hours daily to be effective. An Ozonator “breaks down” contaminants and gases, including ozone, into smaller molecules through a chemical reaction.

The process can take up to 8 hours, depending on the outside air temperature and humidity level.

When it comes to using the Ozonator, The idea is to “pre-condition” the a/c equipment and ducting before use by running it with no load for several hours.

This will remove all the “contaminants” such as dust and grime that have built up over time.

These results will give you a more effective unit that runs more efficiently and much longer between services.

If the unit were not “pre-conditioned” before use, you would have less than stellar results.

So play it safe and run your Ozonator 4-6 hours daily to get good results.

Do You Need Bromine With An Ozonator?

Bromine is often added as a secondary disinfectant in addition to an ozone generator, so I call it a “brominator.” Ozone generators are not magic and cannot kill all forms of bacteria, viruses, and spores.

Most degreasers require an Ozonator for best effects. This usually comes as a package deal with the use of bromine in addition to a chlorine generator.

All three chemicals work together to kill 99% of your water’s bacteria or other contaminants. Bromine is no better than chlorine without an ozone generator, though, so it’s entirely up to you if you need it or not.

If you plan to use an Ozonator for your cleaning system, you will likely need to use a chlorine generator. Many places with too dirty water for an ozone generator will use chlorine or bromine in conjunction with the ozone.

Ozonators are only as effective as the water that goes into them. If the water is dirty, neither the ozone nor bromine will be effective, no matter how hard you try.

If you have really bad water, it’s best to use an Ozonator and a lot of bromine. Bromine is not available in the same concentrations as chlorine, meaning you need more of it to get the same effect.

This is why some people use an Ozonator and a brominator.

Can I Shock My Hot Tub With Bromine?

Yes! Bromine is available in 500-gram bottles from your local pool store or online retailer. It is also known as hydrogen bromide and bromine chloride.

If you have a spa with jets, turn them off before adding bromine or another chemical to the water. If the spa is chemically cleaned, add bromine at least every two months with 30 grams of non-chlorine shock/ 1500 litres of water.

To make this procedure faster, you may use a generator. The standard yellow plug-in gas generators are available in any pool store or online retailer.

You may also use electric shock to generate and sanitize the water since it will produce the same amount of bubbles as a typical spa.

When you have a bromine gas generator, go to your spa and find the drain. Use a funnel to direct the gas inside the drain. Then, run all of your water out by running each jet one by one.

Do You Need To Shock An Ozone Pool?

When that is done, add 18 grams of non-chlorine shock/1500 litres of water into the system. Next, you need to rerun each jet for at least 10 minutes, then just let it sit for 20 minutes before you drain it again.

After the water is drained, wipe down all surfaces in your spa to remove any excess bromine residue.

Repeat this procedure every two months with 30 grams of non-chlorine shock/ 1500 litres of water. If you do not often clean your spa, you may want to shock it monthly with 30 grams of non-chlorine shock/ 1500 litres of water.

5 Pros and Cons of an Ozone Pool System


  1. Quick disinfectant: Ozone kills bacteria just as effectively as chlorine. Chlorine is a widely used disinfectant in swimming pools, but it does not affect some types of viruses.
  2. Prevention: ozone pools can kill any pathogens present before they gain a foothold in your pool, including algae, fungi, and mold.
  3. Low maintenance: No need to empty or clean your pool daily because everyday use will keep it clean and safe for swimming with minimal effort or expense.
  4. Natural: because ozone is produced by normal body functions and is not derived from toxic chemicals, it’s safe for swimmers and the environment.


  1. Not for swimmers with a heightened risk of reaction: Some people are allergic to ozone, so you need to ensure that it isn’t harming your health. If you have asthma or skin problems, you should also ask your doctor whether ozone is safe.
  2. Inserts and liners will need replacing every few years: Because ozone is so effective at killing bacteria, it can do a lot of damage if left in the pool too long – mainly if the water is cloudy or cloudy after rainfall.
  3. So, you’ll have to replace your liner or pool equipment after several years.
  4. An expensive initial investment: you will need to install a special filter, called an ozone generator, along with an ozone system controller before you can use ozone in your pool.
  5. You may also need to replace filters and other equipment more often than you would for a chlorinated pool, which will add to your costs over the long run.
  6. Special maintenance: ozone pools are more delicate than chlorine pools and can only be used if the water is free from sediment and other particles. It would be best to keep your pool free from algae to prevent damage to the ozone generator.
  7. Potentially harmful chemicals: you will need an ozone generator to turn air into ozone, which produces small amounts of potentially harmful chemicals as a byproduct (e.g., formaldehyde).
  8. You can reduce these risks by ventilating the room where you run your generator and by keeping the ozone outlet pipe away from the skin.

Does Ozone Have an Odour?

Yes! Ozone boasts a distinctive smell you can identify even when used in small quantities. This is because the gas has a sharp odor, often described as freshly cut grass.

The smell of ozone is stronger in warmer temperatures, and it can become overpowering if you work with high gas concentrations.

You can use Ozone in various ways: introduce it into the atmosphere to kill bacteria and germs or as a bleaching agent. Several industries employ ozone to help them neutralize odours and contaminants in water and air.

The gas is also used in purifying drinking water, medical equipment, and clothing.

Ozone has the power to oxidize the material it touches. When used as a disinfectant, the gas will break down organic contaminants in the air and water. It also serves to destroy harmful bacteria, viruses, and pathogens.

Most organisms will succumb to an ozone-based disinfection process when exposed for a short period.

Ozone emits a characteristic smell you can recognize even when only small amounts are present. Due to its sharp odor, this gas smells like freshly cut grass. You will also notice a distinctive odour when ozone is used to bleach textiles.

How is Ozone Made?

Ozone is made when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), and there are natural (biogenic) and human-made sources of these gases.

The ozone layer boasts a protective layer in the ozone layer, which is around 30 miles up in the atmosphere. It absorbs the harmful UV radiation from the sun to keep earth living organisms safe.

Ozone can be found in smog during the heat of summer days and is created by cars, power plants, industrial, residential and agricultural sources.

It is not a pollutant in the true sense of that word but rather a reactive gas produced naturally by biological and chemical processes.

Carbon monoxide (CO) is another reactive gas created naturally. NOX and VOC react together to form ozone. These chemicals do not exist by themselves.

The reactive chemicals that make up ozone need something to react with. They most commonly react together to form a pollutant called ground-level ozone.

These gases are also used in everyday items like hair spray, perfume, and deodorant.

Those of us in the tropical areas of the world should be careful when using these products since they could also form ozone if used in the heat of the day during summer.

How does the temperature or humidity of the air affect ozone?

Higher temperatures are generally associated with higher ozone levels, while higher water vapor concentrations are typically associated with higher ozone measurements.

Ozone gas strongly absorbs ultraviolet (UV) radiation and is responsible for many of the sun’s ills, including skin cancers and cataracts.

Ozone at ground level will also increase breathing issues, damage crops, and other living plants, and contribute to environmental degradation.

We must consider its structure to understand the relationship between temperature and ozone. Ozone boasts of three oxygen atoms bound together.

Because of these extra oxygens, this molecule is more chemically active than regular oxygen.

Therefore, it participates in chemical reactions that alter other molecules around it. The most important reaction involving ozone is nitrogen dioxide (NO).

These two molecules react together to become nitric oxide (NO), a gas that does not absorb UV radiation. The reaction between ozone and NO is shown below:

In other words, NO +O3 → 2NO.

The second reaction we must consider is between ozone and other atmospheric chemicals. These compounds are called “reactive oxygen ions” or ROIs. Ozone will dissolve in water (H2O) to form hydroxyl radicals (OH).

Since every molecule will have a different response to temperature, you must experiment to determine the tendency between ozone and temperature.

Is Ozone Safe For My Pool Equipment?

Ozonators are entirely safe in inground and above-ground indoor and outdoor swimming pools. The strict stipulations of the EPA’s regulations require that you store Ozonators for pool use only and not as central heating or air conditioning.

Using an ozone generator will keep your pool clean without the need for chemicals. Maintain a healthy chlorine level using an automatic chemical feeder or a manual pump.

Ozonators are also safe for human, animal, and plant life because all harmful gasses are broken down naturally, leaving only oxygenated water in their wake. They are safe for all pool equipment, including:

  • Pool heating or water filtration pumps
  • Swimming pool equipment such as skimmers, vacuum pumps, and filters
  • Pool chemicals such as chlorine, bromine, and shock
  • Above-ground saltwater pools

Chlorine levels will not rise in your pool, and you can use it the same way you used it. Ozone is a natural product and is entirely safe for all pool equipment.

You do not need to worry about having to add chemicals or spend your valuable time mixing up new chemicals.

Keep note of the potential of ozone staining the side of your pool. The EPA recommends not using ozone until your pool is professionally cleaned.

The cleaner should always use a pool cover and a vacuum to prevent excess dust particles from being sucked into your pool.

How Does the ozone affects water balance?

Normally Ozone has a neutral PH (about 7.0), so it does not affect the PH of the system’s water molecules. However, ozone is a colorless gas that easily attaches to water molecules and forms an ozone molecule (O3) under the influence of UV light.

Ozone is created by combining oxygen gas and O3 in the presence of heat and electrical energy.

The presence of ozone can cause several health effects, including lung damage, but can also have beneficial effects by inhibiting bacterial growth and plant disease development.

Ozone is a potent oxidizer that can break the bonds of several molecules and free radicals. Although ozone is colorless and does not affect the pH of the water, it can oxidize substances in the water, creating free radicals.

In open ponds, ozone increases oxygen levels by encouraging photosynthesis. The gas can also remove waste from ponds by reacting with organics, such as ammonia (NH3), nitrite (NO2-), and phosphorus (P).

It also reduces filamentous algae by destroying their cell walls.

In closed systems such as recirculation aquaculture (RAS), ozonation is used to purify water. It also removes nitrogenous waste and reduces the production of nitrites and ammonia in recirculating aquaculture systems (RAS).

In addition, ozone can increase fish growth by increasing dissolved oxygen levels, which is critical for proper development.

What Special Maintenance Does Ozone Require?

Ozone generation units require a system to clean and remove the humidity from the air.

The dehumidifier removes the humidity by removing any moisture that may react with ozone and create toxic fumes, known as humidity control.

The cooling coil on the AC unit reduces the cooling coil temperature so that it will not freeze due to ice buildup within the cooling coils of the AC unit.

When these two processes are in place, an ozone production system requires little or no maintenance. The only other maintenance required is to filter the water in the unit and add a biocide to prevent algae or mold growth.

Smaller units may have filters that only require cleaning once every few months. Units with ozone injectors may need to be changed out periodically, just as you would replace an air filter on your furnace.

Ozone systems require filters to remove dust, pollen, mold, and other toxins from the air. 

Some ozone systems also use a water-based filter system to remove particles ranging from 0.3 to 0.4 microns, including bacteria, viruses, salt, pollen, and mold spores.

It is important to note that a certified HVAC technician should perform regular AC service for efficiency, performance, and safety reasons, not ozone system maintenance.

Will Ozone Generator Help The Ozone Layer?

Many devices on the market boast air purification ability. Ionizer Xtreme, an ozone generator, currently makes the most popular device.

The generators produce a slight “plume” of purified oxygen that can disperse into an area of about 7 feet in diameter when you turn it on for around 10 minutes.

The company claims that the ozone will “clean” the air of bacteria, viruses, and germs. The product cleans the air from airborne harmful microorganisms and particles, relieves dry, stuffy noses, and helps with breathing in many ways.

It also kills airborne mold spores and removes pet dander, dust mites, and pollens. It is an alternative to a humidifier and an air purifier that sterilizes mold spores on walls and floors and kills fleas on your pets.

The process of purification is simple. It starts with a chemical reaction between CO & O2 or H2O and bromine or chlorine.

This generates several ozone molecules that have been measured as producing as much as 81,000,000% oxygen (at 0.25 oz/m3). The high amount of oxygen kills airborne mold spores, mites, germs, and bacteria.

The results are a discharge of a high amount of oxygen combined with the ozone gas into the air via a regular outlet.


Ozone pool systems can significantly improve water quality and breathe life into your yard, house, and family.

These systems are designed to produce ozone gas at a controlled level to kill harmful microorganisms and microbes while purifying the air around you.
