Inflatable pools are a fun, affordable, and convenient way to enjoy a cool dip during the summer. However, many pool owners, especially those new to inflatable pools, often ask: Can you put anything in an inflatable pool to keep it clean? The short answer is yes—but not everything is safe, effective, or necessary. In this article, we’ll explore the best ways to maintain clean and safe water in an inflatable pool, from chemical treatments to natural alternatives, pool accessories, and cleaning tips.
By understanding what you can and should put in your inflatable pool to keep it clean, you’ll be able to ensure hygiene, prolong the life of your pool, and enhance the overall enjoyment of your backyard oasis.
Understanding the Basics of Inflatable Pool Cleaning
Before diving into specific cleaning methods or products, it’s essential to understand the fundamental needs of an inflatable pool. Unlike permanent in-ground or even rigid above-ground pools, inflatable pools are typically smaller, shallower, and not equipped with complex filtration systems.
Why Inflatable Pools Need Special Cleaning Attention
Because of their size and structure:
- Water can heat up quickly, promoting algae and bacterial growth.
- They are more prone to contamination from sweat, sunscreen, dirt, and insects.
- Most inflatable pools have limited or no built-in filtration systems.
This makes it crucial to be selective and cautious with what you put in the water. Overuse of harsh chemicals or improper cleaning methods can damage the PVC or vinyl material of the pool, degrade water quality, or even pose health risks.
Safe and Effective Chemical Treatments for Inflatable Pools
Chemical treatments are among the most reliable ways to keep pool water clean and safe. However, not all chemicals are suitable for inflatable pools, and dosage matters a great deal.
Chlorine: A Popular but Careful Choice
Chlorine is a go-to disinfectant for most pool owners due to its effectiveness in killing bacteria, algae, and other pathogens. But in an inflatable pool, you should use it with care.
Types of chlorine suitable for inflatable pools include:
- Chlorine tablets (slow-dissolving, often placed in a floating dispenser).
- Granular chlorine (used for shock treatments).
- Liquid chlorine (sodium hypochlorite), typically used for smaller pools or emergency disinfection.
Before using chlorine, always:
- Follow the manufacturer’s instructions for dosage.
- Test the water for proper pH levels (the ideal range is 7.2 to 7.6).
- Use a dedicated pool test kit to check chlorine levels (ideal range: 1–3 ppm).
Too much chlorine can irritate the skin and eyes, and may also weaken the inflatable pool’s material over time. Always consider the size of the pool when calculating chlorine use.
Bromine: A Gentler Alternative
Bromine is another sanitizing chemical often used in hot tubs and spas, but it can also be a good fit for inflatable pools. It works well in warm water and is less irritating than chlorine.
However, bromine:
- Is more expensive than chlorine.
- Is not as effective in direct sunlight compared to stabilized chlorine.
- Does not dissipate as easily and requires a separate bromine test kit for accurate monitoring.
If you’re looking for an option that’s gentle on skin and still effective for sanitization, bromine might be a suitable alternative.
Pool Shock: Essential for Deep Cleaning
Shocking your inflatable pool is a process that involves adding a concentrated dose of chlorine or non-chlorine shock to oxidize contaminants. It’s essential after heavy use, bad weather, or if the water starts to look cloudy.
There are two major types of pool shock:
| Shock Type | Pros | Cons |
|---|---|---|
| Chlorine-based (Calcium Hypochlorite) | Kills bacteria and algae effectively | Can raise calcium levels and cloud water |
| Non-chlorine (Potassium Monopersulfate) | Gentle, no wait time to swim | Doesn’t kill algae |
When using chlorine-based shock, make sure to run the pool filter (if you have one) afterward or manually circulate the water.
Natural and Non-Chemical Options for Maintaining Pool Hygiene
Some pool owners prefer to avoid or minimize chemical use, especially when children or pets are frequent users. There are natural alternatives, but their effectiveness depends on use frequency and the environment.
Mineral-Based Systems: A Blend of Nature and Technology
Mineral-based pool systems use silver and copper ions to purify water. These systems:
- Are effective at controlling algae and bacteria.
- Reduce the need for chlorine or bromine usage by up to 50%.
- Are easy to install and long-lasting.
However, they may be more cost-effective for slightly larger inflatable pools and require periodic refilling of the mineral cartridge.
Saltwater Chlorinators: Not Always Ideal for Inflatable Pools
Saltwater systems use a salt cell to generate chlorine through electrolysis. While they’re popular in traditional pools, they are not commonly recommended for inflatable pools due to:
- Higher upfront cost.
- The risk of salt corrosion to the PVC material over time.
- Increased maintenance and space requirements.
If you’re considering a saltwater system, verify compatibility with your pool model and material before installation.
Enzymes and Oils: Enhancing Pool Cleanliness Naturally
Enzyme-based treatments break down oils, lotions, and organic matter in the water, reducing scum lines and improving water clarity. While they don’t sanitize, they are great for:
- Enhancing chemical efficiency.
- Reducing chemical usage.
- Extending the cleanliness between water changes.
Essential oils, though less commonly used, can add a pleasant fragrance. However, they may leave behind an oily residue or interfere with chemical balance, so always use them cautiously.
Physical and Mechanical Ways to Stay Clean
Cleaning an inflatable pool doesn’t end with chemicals. Ongoing maintenance through physical and mechanical methods is just as essential to prolong water freshness and pool durability.
Pool Covers: First Line of Defense
Using a pool cover or solar blanket while the pool is not in use can significantly reduce the amount of debris and UV exposure. The benefits include:
- Preventing leaves, dirt, and bugs from entering the water.
- Promoting heat retention in cooler weather.
- Reducing evaporation and water waste.
- Boosting UV protection, especially for chlorine-treated water.
Cover your pool every night or whenever it’s idle to maintain optimal cleanliness.
Skimmers and Water Clarifiers
A manual or automatic skimmer helps remove floating debris and insects from the water surface. Water clarifiers or filters can be used intermittently to remove fine particles and restore clarity.
If your inflatable pool has a pump or filter system, using a clarifier additive can improve performance and reduce chemical strain.
Cleaning the Pool Surface Manually
Even with chemical and physical maintenance, the inner and outer surfaces of an inflatable pool require periodic cleaning:
Inner Surface Cleaning Steps:
- Drain the pool and rinse thoroughly with fresh water.
- Use a mild soap or a specialized vinyl cleaner.
- Scrub gently with a soft brush—avoid abrasive tools.
Clean the base regularly to prevent dirt buildup and mold growth, especially if the pool is used on grass or soil.
What Should You Avoid Adding to Your Inflatable Pool?
While many substances can help maintain cleanliness, some should be avoided at all costs. These can ruin your inflatable pool or pose health risks.
Bleach: A Risky Substitute
Bleach contains sodium hypochlorite, similar to liquid chlorine, but household bleach also contains other additives and fragrances. These can damage the inflatable pool material or cause skin irritation.
If using bleach, it must be unscented, with at least 5–6% sodium hypochlorite, and carefully dosed. Always consult a pool expert before substituting bleach for pool-grade chlorine.
Vinegar: Limited Efficacy
Apple cider vinegar or white vinegar has some mild antibacterial properties, but it’s not effective enough for sanitizing pool water. It may help with cleaning the pool surface, but adding it to the water won’t maintain disinfectant levels required for safe swimming.
Baking Soda: Better for pH Adjustment
Baking soda (sodium bicarbonate) is often used in pools to raise alkalinity. When properly used, it helps stabilize pH levels, which in turn helps chlorine work more efficiently.
However, baking soda is not a disinfectant, and using it as a primary cleaning agent is not advisable.
Dish Soap, Detergents, and Soaps: Avoid in the Water
While great for cleaning the pool’s material outside of use, dish soap or laundry detergent should never be used to clean water in the pool. They can create foam and suds and may contain chemicals that are unsafe for skin contact or inhaling.
Best Practices for Inflatable Pool Maintenance
Keeping an inflatable pool clean involves more than choosing the right products. It also includes forming habits and routines that protect the pool, the water, and the people engaging in it.
Don’t Let Water Sit Too Long
Even with chemicals, stagnant water will eventually degrade. In general, it’s best to change the water every 2–3 days in smaller pools and weekly at most in larger inflatable pools. This prevents biofilm buildup, reduces chemical dependence, and refreshes the pool experience.
Shower Before Swimming
Encourage swimmers, especially children, to rinse off before entering the pool. Body oils, lotions, and sweat introduce contaminants that consume chlorine and make it less effective.
Keep the Pool Location Clean
Choose a shaded area if possible and regularly clean the surface around the pool. Removing standing water around the pool base prevents mosquitoes and pests from becoming a problem. Use non-toxic repellents or herbs like citronella to keep bugs away naturally.
Regular Testing and Adjustments
Using a pool test kit or test strips to monitor chemical levels is crucial. Weekly pH and chlorine testing can catch imbalances before they become major issues.
Proper Storage After Use
After the swim season ends, cleaning and storing your inflatable pool properly can extend its life dramatically. Drain it completely, wash, dry thoroughly, and store in a cool, dry place away from sunlight and moisture.
Additional Tips for a Healthier and Cleaner Inflatable Pool
Beyond the basic strategies, here are some advanced yet simple suggestions to elevate your inflatable pool care routine:
Use a Water Sanitizer with UV Light
There are compact UV water sanitizers designed for small pools. These units use ultraviolet light to inactivate bacteria and algae spores, reducing the need for chemical sanitizers.
Consider Ozone Generators
Ozone (O3) is a powerful oxidizer that works alongside chlorine to break down organic contaminants. While more common in full-size pools, ozone generators are starting to appear in miniaturized versions for small inflatable pools.
Add a Compact Pool Sand Filter
Even the smallest above-ground or inflatable pools can benefit from a basic sand or cartridge filter. When paired with a small pump, you can maintain cleaner water with less frequent changes and reduce chemical dependency.
Use Biodegradable Pool Products
If you’re environmentally conscious, opt for biodegradable pool skimmer bags, enzyme clarifiers, and phosphate-free algaecides. These products help minimize your environmental impact while still maintaining hygiene.
Teach Kids about Pool Etiquette
Education goes a long way. Teach children not to:
- Drink pool water.
- Spit or urinate in the pool.
- Bring toys (especially rubber ducks) into the pool without regular washing.
This not only helps with cleanliness but also encourages sustainable habits from an early age.
Conclusion: Balance is Key to Inflatable Pool Care
So, can you put anything in an inflatable pool to keep it clean? The answer is a nuanced “yes”—with emphasis on what, how much, and why.
For the best results:
- Balance chemical use with physical cleaning habits.
- Know the differences between sanitizers, clarifiers, and natural products.
- Follow manufacturer guidelines for both the pool and products used.
- Never compromise on safety—safe water is clear, odorless, and maintains proper balance.
Ultimately, the cleanliness of your inflatable pool comes down to consistent maintenance, smart choices, and understanding the specific needs of your pool setup. Whether you use chlorine, natural alternatives, or a combination of both, the goal is always the same: healthy, clean, and enjoyable pool water from one swim session to the next.
By taking the time to understand what to do—and what to avoid—you’ll not only keep your inflatable pool clean, but you’ll also ensure it lasts for many summers to come.
Can I use bleach in an inflatable pool to keep it clean?
Yes, you can use bleach in an inflatable pool, but it must be done carefully and in the right concentration. A diluted bleach solution can help kill bacteria and algae, ensuring the water stays clean and safe for swimming. The general recommendation is to use approximately 1/8 cup of regular-strength, unscented bleach per 100 gallons of water. Always mix the bleach thoroughly in a bucket before adding it to the pool, and avoid direct contact with the vinyl surface to prevent damage.
However, using bleach isn’t a substitute for regular cleaning and water replacement. Over time, contaminants build up, and the water will need to be fully drained and refilled. It’s also essential to test the water’s pH after adding bleach, as bleach can affect water balance. If you’re not comfortable handling chemicals, there are alternative solutions such as non-chlorine shock treatments or natural pool cleaners that may be safer for frequent use.
Is it safe to add chlorine tablets to an inflatable pool?
Chlorine tablets are a common and effective way to disinfect pool water, including in inflatable pools, but they must be used correctly. Since chlorine tablets are concentrated, they should ideally be used with a floating dispenser or erosion feeder to control their dissolution and prevent them from coming into direct contact with the inflatable pool’s floor, where they may bleach or damage the vinyl material. Maintaining the proper chlorine level—typically between 1 and 3 parts per million—is crucial to keeping the water clean and swimmers safe.
It’s also important to monitor the water’s pH, which should remain between 7.2 and 7.6, to ensure the chlorine works effectively. If the pH is too high or too low, chlorine’s sanitizing power is reduced. Always store chlorine tablets in a cool, dry place away from other chemicals, and avoid exposing children or pets to them. While chlorine is an effective sanitizer, some swimmers may be sensitive to it, so alternatives can be considered depending on user preference and skin sensitivity.
Can I use vinegar in an inflatable pool to clean or sanitize it?
White vinegar is a natural cleaning agent and can be used for occasional cleaning of the inflatable pool’s surfaces or for removing mineral deposits and mildew after the pool has been drained. However, it is not a strong enough disinfectant to maintain clean water while the pool is in use, especially under heavy swimmer loads or in warm weather when algae and bacteria can grow rapidly. Vinegar may help with slight discoloration and odor removal, but it should not replace proper sanitizers like chlorine or bromine.
To use vinegar for cleaning the inflatable pool structure itself, mix one part white vinegar with one part water and apply it to the affected area. Scrub gently and rinse thoroughly with clean water before refilling the pool. Do not add vinegar directly to the water intended for swimming, as it may cause skin irritation and is not designed to sanitize in that form. For long-term water cleanliness, stick with tested pool-specific chemicals or alternative sanitizing systems.
What natural alternatives work for keeping inflatable pool water clean?
Some natural or eco-friendly alternatives can help keep inflatable pool water clean, particularly for smaller pools or shallow kiddie pools where swimmers don’t stay in the water for extended periods. One option is using a mineral-based purification system, like silver or copper ionizers, which can help control bacteria and algae growth. Another alternative is hydrogen peroxide-based sanitizers, which can act as an oxidizer and help control organic contaminants without the harshness of chlorine.
UV sterilizers and ozonators are also options, though they tend to be more expensive and may require more setup. These devices use light or ozone gas to break down pathogens in the water. Keep in mind that natural options still may need help from mechanical filtration and regular water changes to work effectively. While these methods reduce chemical use, they may not fully replace it, especially if the pool is used by many swimmers or in hot conditions where bacteria multiply quickly.
How often should I change the water in an inflatable pool to keep it clean?
Ideally, you should change the water in an inflatable pool every few days, depending on how often it’s used and weather conditions. Pools that are used heavily or exposed to sunlight and dirt can become contaminated quickly. Even with proper sanitization, contaminants like sweat, sunscreen, and debris can build up in the water, making it a breeding ground for bacteria and algae.
Draining and refilling the pool regularly is the most effective way to reset water quality. If you use chemical sanitizers like chlorine or alternatives, it still won’t completely eliminate all dissolved solids. When the water becomes cloudy, starts to smell, or feels slippery, it’s definitely time for a change. Between water changes, regular skimming, surface wiping, and cleaning the filter or any pump system can extend the time between full drainages and keep the user experience safer and more pleasant.
Can I use a saltwater system in an inflatable pool?
Saltwater systems can be used in inflatable pools, but they require a pool with a compatible filtration and chlorination system. The system works by using a saltwater chlorinator, which converts salt into chlorine to sanitize the water automatically. While this creates a more balanced chlorine environment that is gentler on the skin and eyes, it still relies on chlorine as the main sanitizing agent.
Unfortunately, most inflatable pools do not come with built-in salt chlorinators or advanced filtration systems. If you’re interested in using a saltwater system, you’ll need to choose a small, portable salt chlorinator compatible with your pool’s pump system. Also, ensure the inflatable pool’s materials are chlorine-resistant since the chlorine generated by salt systems can still degrade vinyl over time. This method works best for larger inflatable pools equipped with a proper pump and filter system.
Is it okay to add algaecide to an inflatable pool?
Algaecide can be a helpful supplement to regular sanitization in an inflatable pool, especially if you’re dealing with or trying to prevent algae growth. Algaecide works by killing algae spores and preventing their spread, which can be particularly useful in warm or humid climates where algae tend to grow faster. It should not be used as a standalone cleaner but rather as a part of a regular pool care routine that includes chlorine or an alternative sanitizer.
When adding algaecide, be sure to choose a product that’s safe for inflatable pools, ideally one that’s non-metallic and appropriate for small or above-ground pools. Follow the manufacturer’s instructions carefully, as using too much can cause foaming or damage pool surfaces. After applying algaecide, run the filtration system if available, or agitate the water to help distribute the chemical evenly. Algaecide is most effective when used after brushing the pool walls and allowing time for the product to circulate.
