Chlorine Treatment for Dunk Tanks
Chlorine is the go-to solution for treating dunk tank water, and it’s easy to see why. It’s affordable, effective, and widely accessible, making it a reliable choice for keeping water safe. But using chlorine correctly is key to maintaining clean water and avoiding potential health risks.
How Chlorine Works
Chlorine works by targeting harmful microorganisms in the water. When introduced, it disrupts the cell walls of pathogens, effectively destroying them.
"Chlorination is the process of adding chlorine to drinking water to kill parasites, bacteria, and viruses… Using or drinking water with small amounts of chlorine does not cause harmful health effects and provides protection against waterborne disease outbreaks."
To keep water safe, maintaining the right chlorine levels is essential. For regular water storage, a chlorine residual of 1 to 2 PPM is typically enough to protect against most harmful microorganisms. However, when dealing with new or potentially contaminated tanks, a stronger dose – 50 to 100 PPM – is recommended for shock chlorination to eliminate more stubborn pathogens.
Pros of Chlorine Treatment
Chlorine offers several benefits that make it a top choice for dunk tank operators:
- Cost-effective: A little chlorine goes a long way, treating large amounts of water without breaking the bank.
- Proven reliability: Chlorine has been trusted for over a century in public water systems. Both the CDC and WHO recognize chlorine levels up to 4 PPM as safe for drinking, which provides a generous margin for recreational use.
- Residual protection: Unlike some treatments, chlorine continues to work even after the initial application, offering ongoing safety.
Cons of Chlorine Treatment
While chlorine is effective, it’s not without its drawbacks. Skin and eye irritation is a common issue, especially at higher concentrations. People with sensitive skin or conditions like eczema may experience redness, itching, or discomfort.
There’s also the risk of clothing damage. Pool expert JasonLion notes that chlorine levels above 5 PPM, particularly without stabilizers like cyanuric acid (CYA), can harm clothing and irritate the skin.
Best Practices for Chlorine Use
To maximize chlorine’s benefits while minimizing risks, follow these best practices:
- Inspect the tank first: Check for cracks, leaks, or other issues that could compromise water quality. Clean the tank thoroughly by scrubbing the interior with a strong chlorine solution (½ gallon of household bleach or ¼ gallon of pool chlorine per 5 gallons of water).
- Add chlorine gradually: Avoid overdoing it. As JasonLion advises, “I wouldn’t add more than 5 ppm of chlorine at one time. Levels higher than that, with no CYA, can damage clothing and cause skin irritation”.
- Test regularly: Use test strips or digital meters to ensure chlorine levels stay between 1 and 2 PPM.
- Choose stabilized chlorine products: Dichlor or trichlor compounds, which include cyanuric acid, help protect chlorine from UV degradation and reduce the risk of over-chlorination.
- Replace water periodically: Routine water changes help prevent organic buildup and reduce the need for excessive chemical treatments.
Alternative Water Treatment Methods
When it comes to water treatment, alternatives can address concerns like skin sensitivity, environmental considerations, and maintenance challenges.
Bromine
Bromine is an effective sanitizer that works by ionizing contaminants, making it particularly suitable for warm water environments.
One of bromine’s standout features is its gentler nature compared to chlorine. It has a milder smell and is less likely to irritate the skin, making it a good choice for events involving participants with sensitive skin.
However, bromine has its drawbacks. It tends to be more expensive than chlorine and is harder to rinse off the skin after use. Additionally, bromine cannot be stabilized against UV light, which means it degrades more quickly when exposed to direct sunlight.
| Factor | Chlorine | Bromine |
|---|---|---|
| Cost | Less expensive | More expensive |
| Smell | Strong odor | Less odor |
| pH Stability | Harder to maintain | Easier to maintain |
| UV Resistance | Can be stabilized | Cannot be stabilized |
| Skin Removal | Washes off easily | Harder to remove |
For those looking beyond chemical treatments, there are non-chemical methods that also ensure effective water sanitation.
UV Disinfection
UV disinfection uses ultraviolet light to target and disrupt the DNA and RNA of pathogens, eliminating up to 99.99% of harmful microbes. It is particularly effective against chlorine-resistant microorganisms like cryptosporidium and giardia.
This method is eco-friendly, requires minimal maintenance, and doesn’t produce harmful byproducts. However, UV disinfection has its limitations. It offers no residual protection, meaning it only treats water that passes directly through the UV system. Additionally, UV systems rely on electricity and may require pre-treatment if the water is cloudy or turbid.
For a solution that combines UV technology with oxidation, hydrogen peroxide-based systems are worth exploring.
Hydrogen Peroxide-Based Systems
Hydrogen peroxide (H₂O₂) provides another alternative, often considered safer than traditional sanitizers. As a strong oxidizer, it effectively breaks down organic matter while producing fewer harmful byproducts compared to chlorine.
When combined with UV light, hydrogen peroxide generates hydroxyl radicals – highly reactive molecules that rapidly destroy microorganisms. As industry expert Ashkahn explains:
"Basically the UV and hydrogen peroxide when used together is really the only way you want to use hydrogen peroxide… the UV is doing the heavy lifting".
Hydrogen peroxide systems work faster than chlorine, leave no chemical aftertaste, and remain effective across a broader pH range. However, they require specialized equipment and come with higher initial costs.
Whether opting for bromine, UV systems, or hydrogen peroxide-based treatments, each method offers distinct advantages. Selecting the right approach depends on factors like event requirements, budget, and operational demands. These alternatives provide operators with the flexibility to maintain water quality while addressing specific needs.

Key Insights
Cost Considerations: Chlorine stands out as a budget-friendly option, costing just $2–$5 per gallon for a 5–7% concentration, making it ideal for those on a tight budget. On the other hand, hydrogen peroxide requires a higher upfront cost of $10–$14 per gallon for a 7% solution. However, because it works about twice as fast as chlorine and requires lower concentrations (0.3–0.5 PPM versus chlorine’s 0.6–1.0 PPM), some of the cost difference can be offset.
Effectiveness: Chlorine is highly effective against most pathogens, though it may not eliminate all. UV disinfection, however, achieves an impressive 99.99% kill rate for bacteria and viruses. That said, UV doesn’t provide residual protection once the water leaves the treatment system.
Safety: Bromine is a gentler alternative for those with sensitive skin or eyes, though it produces more toxic byproducts. Saltwater systems that generate chlorine can also increase bromine-related byproducts by up to 70% due to bromide impurities in the salt.
Best Use Cases
- Chlorine: Perfect for high-volume events like carnivals or festivals where cost is a major factor. It’s highly effective and can handle shock treatments for rapid water recovery after heavy use.
- Bromine: A better choice for indoor or shaded environments, especially when catering to participants with sensitive skin or concerns about strong odors. However, bromine’s efficiency drops in direct sunlight, so it’s less ideal for outdoor daytime events.
- UV Disinfection: Ideal for situations requiring strict environmental standards or when dealing with chlorine-resistant pathogens. With a 99.99% kill rate, UV systems are great for high-risk scenarios. However, they should be paired with a backup chemical sanitizer since they don’t leave residual protection.
- Hydrogen Peroxide: A chlorine-free option that works well for events needing fast water turnaround. Its quick action and wide pH tolerance make it a solid choice despite the higher upfront costs.
- Combination Approaches: For maximum protection, consider combining methods. For instance, using ozone alongside chlorine can reduce chlorine consumption by 40–60%, improving overall pathogen control while still maintaining residual disinfection.
Ultimately, your choice will depend on your specific needs, including budget, safety requirements, and operational priorities. Each method has its strengths, so weigh the options carefully to find the best fit.
Maintenance and Safety Considerations
Keeping dunk tank water clean and safe requires consistent maintenance and strict safety practices, no matter which water treatment method you’re using. While the specific steps may vary depending on the system, there are a few universal practices that apply across the board.
Routine Maintenance Practices
Water Quality Testing is the cornerstone of any maintenance routine. Regular testing of both the tank water and tap water helps identify contaminants and maintain safe conditions. For chlorine-based systems, aim for a pH between 7.4–7.8 and alkalinity levels between 80–120 ppm. If you’re using a copper ionization system, keep the pH between 7.0–7.4 with alkalinity levels around 60–80 ppm.
Regular Water Changes should be planned based on factors like season, tank usage, and how often the tank is used for events.
Tank Sanitization should happen at least twice a year under normal circumstances. During periods of frequent use, additional cleanings are necessary. For tanks that collect rainwater, an annual deep cleaning is essential to remove sludge, which can harbor harmful bacteria.
Chemical Monitoring is another critical step. Create a schedule for checking and adjusting chemical levels based on your test results. Keep in mind that municipal water often comes pre-chlorinated. Also, outdoor tanks are exposed to sunlight, which breaks down chlorine, meaning you might need to adjust levels more often.
Safety Procedures
Beyond maintenance, safety protocols are key to ensuring the dunk tank operates smoothly and safely. Always follow the manufacturer’s guidelines and local rules for handling chemicals. Store chemicals in cool, dry places, away from sunlight and materials they might react with. When handling chemicals, wear proper safety gear like gloves and eye protection.
Equipment Safety involves regular upkeep, such as replacing UV lamps or inspecting electrical components, depending on the system.
User Safety is equally important. Clearly post any warnings about recent chemical treatments and ensure that chemical levels are within safe limits. Emergency plans should also be in place. For example, test the water immediately if someone reports skin or eye irritation. Keep contact information for local health departments and poison control centers handy.

FAQs
What’s the difference between chlorine and bromine for treating dunk tank water, and how do I decide which to use?
Chlorine and bromine are both solid options for keeping dunk tank water clean, but each has its strengths depending on the situation. Chlorine works quickly to eliminate contaminants, making it a top pick for outdoor dunk tanks exposed to sunlight. That said, it tends to break down faster in high temperatures, which means you might need to reapply it more often. Bromine, on the flip side, holds up better in warmer water (up to 86°F) and lasts longer overall. It’s also gentler on the skin and eyes, which is a big win for events with kids or anyone with sensitive skin.
When choosing between the two, think about your dunk tank’s setup – what’s the water temperature? Is it in direct sunlight? And how much upkeep are you prepared to handle? If you’re planning an event and want a no-stress solution, companies like Bouncy Rentals USA offer clean, sanitized dunk tanks to make your day easier and more enjoyable.
What is UV disinfection in water treatment, and why doesn’t it offer long-lasting protection like chlorine?
UV disinfection is a method of water treatment that relies on UV-C light to neutralize harmful microorganisms. By damaging their DNA, it stops these organisms from reproducing or causing harm. This approach works quickly, effectively eliminating bacteria, viruses, and other pathogens during the moment of exposure.
That said, UV disinfection differs from chemical treatments like chlorine in one key way: it doesn’t leave behind a residual disinfectant. In other words, once the water is treated, it’s not protected from potential recontamination. For situations where water might encounter new contaminants over time, chemical treatments like chlorine are often the go-to choice for continuous protection.
What kind of maintenance do hydrogen peroxide water treatment systems need, and are they more cost-effective than chlorine over time?
Hydrogen peroxide water treatment systems need consistent maintenance. This includes refilling the peroxide solution, which typically costs between $20 and $50 per month for residential use, and performing occasional system checks or replacing parts. While the upfront cost of a hydrogen peroxide system is higher compared to chlorine systems, it comes with perks like quicker action, better efficiency, and a more eco-friendly approach. These factors often translate into lower long-term expenses thanks to reduced maintenance needs and fewer replacements.
On the other hand, chlorine systems may be less expensive initially, but they often demand more frequent upkeep and chemical refills, which can drive up costs over time.
