Chlorine-Free Pool Maintenance: The Natural Guide for Sensitive Skin
Home pool with babies or sensitive skin: the summer challenge
Having your own pool is a luxury many families enjoy in summer. However, when there are babies, young children, people with atopic dermatitis, or allergy-prone skin at home, conventional chlorine can become a problem: itchy eyes, skin irritation, dryness, redness, and that characteristic smell that many sensitive skins simply cannot tolerate. The good news is that there is a way to keep your pool water clean, safe, and balanced, minimizing these effects, without having to give up disinfection.
At Puerto Verde, we have developed a line of 100% natural auxiliary pool products, specifically designed for those who need gentler water. Below, we explain in detail why chlorine is so irritating, what role these natural products play, and how to use them to enjoy a safe pool all season long.
Why chlorine irritates skin and eyes
Chlorine itself is not the sole cause of irritation. In reality, most skin and eye problems are not caused by free chlorine, but by chloramines, compounds that form when chlorine reacts with organic matter in the water: sweat, sunscreens, urine, and dead skin cells from bathers.
How chloramines form and why they are so irritating
Chloramines are much more aggressive irritants than free chlorine itself. They are responsible for the characteristic "pool" smell, eye irritation, itchy skin, and the reactions experienced especially by people with atopic or sensitive skin. Furthermore, the more chloramines there are in the water, the more chlorine must be added to compensate for the loss of disinfectant effectiveness, thus creating a cycle that progressively worsens the situation.
Therefore, the key to reducing irritation is not to eliminate chlorine, but to maintain the water in an optimal chemical balance so that chlorine works efficiently at the lowest possible concentration. And that is exactly where Puerto Verde's natural products come in.
When the water's pH rises above 7.6, chlorine rapidly loses effectiveness: at pH 8.0, it only works at 20% of its capacity. As a result, more chlorine is added to compensate, which increases the concentration of chloramines and, therefore, irritation.
Similarly, when the water's alkalinity is unstable, the pH constantly fluctuates, making it impossible to maintain a lasting balance. Keeping the pH between 7.2 and 7.4 and alkalinity between 80 and 120 ppm is the most effective way to reduce irritation without sacrificing disinfection.
The three natural Puerto Verde products for your pool
Our range of pool products is formulated with 100% natural ingredients, free of aluminum sulfate, synthetic chemicals, and completely safe for sensitive, atopic skin, and babies. Below, we present each of them:
Natural pH raiser
Raises the pH gently and controllably to the optimal range (7.2-7.4) so that chlorine works at maximum efficiency with the lowest possible dose.
See product →Natural alkalinity raiser
Stabilizes water alkalinity between 80 and 120 ppm so that the pH remains stable and does not fluctuate, reducing the need for continuous corrections.
See product →Natural flocculant
Aggregates suspended particles that the filter does not retain to achieve crystal-clear water. Sulfate-free and suitable for sensitive and atopic skin.
See product →All three products are formulated without aluminum sulfate, synthetic surfactants, or any compound that could accumulate in the water and come into contact with vulnerable skin. Being 100% biodegradable, they also do not generate toxic waste when the pool is emptied at the end of the season.
Furthermore, by improving the chemical balance of the water, they allow for working with lower chlorine concentrations, which directly translates to fewer chloramines, less irritation, and a much more comfortable bathing experience for the entire family.
What each product does and why they work together
To understand why this combination of products is so effective, it is important to know what role each water parameter plays in the bathing experience and skin health:
The alkalinity raiser: the basis of everything
The total alkalinity of the water acts as a pH buffer: when it is in the correct range (80-120 ppm), the pH remains stable and does not rise or fall abruptly due to the addition of products, rain, or intensive use. Without adequate alkalinity, the pH constantly fluctuates, making it impossible to maintain water balance.
Therefore, the first step is always to adjust alkalinity before correcting pH. Our natural alkalinity raiser achieves this stabilization without aggressive chemical compounds, which is also especially important in pools with sensitive skin where any irritating agent in the water should be minimized.
The pH raiser: the balance that protects the skin
Once alkalinity is stabilized, the next step is to maintain the pH between 7.2 and 7.4. This range is not arbitrary: at this pH, chlorine works at its maximum disinfecting efficiency, and consequently, a much lower dose is needed to keep the water safe.
Furthermore, at pH 7.2-7.4, the water is practically isosmotic with human skin and eyes, which means it does not generate the osmotic irritation caused by very acidic or very basic water. In other words, maintaining the correct pH is the most direct measure to reduce itchy eyes and skin irritation after bathing.
The natural flocculant: crystal clear water without aluminum
Suspended particles not only cloud the water but also consume chlorine by reacting with it, generating more chloramines and reducing disinfecting effectiveness. By eliminating these particles through natural flocculation, the water's chlorine demand is reduced, and therefore, the formation of irritating byproducts.
Unlike conventional flocculants with aluminum sulfate, our natural flocculant does not add any metallic compounds to the water, which is especially relevant for babies and people with atopic skin who spend a lot of time in contact with pool water.
Who especially benefits from this natural approach
Although anyone can enjoy the benefits of better balanced water, there are groups for whom the use of these natural products makes a particularly noticeable difference:
Babies and young children
- Babies' skin is 3 to 5 times more permeable than an adult's, which means they absorb any compounds present in the water more easily.
- Their hepatic and renal detoxification systems are not yet fully mature, so exposure to metals like aluminum and chlorine byproducts has a proportionally greater impact.
- Additionally, babies have a larger body surface area relative to their weight, further amplifying skin exposure during bathing.
People with atopic dermatitis
- The skin barrier of atopic skin is compromised, making it much more vulnerable to irritating agents in the water: chloramines, dissolved metals, and pH imbalances.
- Excessive chlorine removes the skin's natural sebum and alters its microbiome, aggravating atopic flare-ups. Reducing chlorine concentration through good water balance helps minimize this effect.
- Therefore, maintaining pH and alkalinity in optimal ranges, combined with an aluminum-free flocculant, is the most suitable combination for pools frequented by people with atopic skin.
People with allergies and sensitive skin
- Chloramines are one of the main triggers of skin reactions in people with a history of allergies. By maintaining water balance with natural products, their formation is significantly reduced.
- Furthermore, many sensitive people react to the aluminum sulfate in conventional flocculants, which can manifest as itching, redness, or hives after bathing. Our natural flocculant completely eliminates this risk.
Weekly natural maintenance routine for your pool
To achieve the best results with these products and enjoy clean, non-irritating water all season long, we suggest a simple and easy-to-follow weekly routine:
Always adjust alkalinity first and then pH, never the other way around. If you correct the pH before stabilizing alkalinity, the corrected value will not be maintained and you will have to repeat the adjustment continuously. Stable alkalinity between 80 and 120 ppm makes pH much easier to maintain in the optimal range.
Furthermore, always apply the flocculant with the pH already corrected and in the appropriate range. This way, its clarifying effectiveness is maximized, and flocs form much faster.

Frequently asked questions about pool maintenance without harsh chlorine
Below, we answer the most common questions about using natural products for pool maintenance:
Do these products eliminate the need for chlorine?
They do not eliminate the need for chlorine, but rather optimize the water so that chlorine works with the greatest possible efficiency at the lowest concentration. By maintaining pH and alkalinity within optimal ranges, the available free chlorine is maximized even with low doses, which reduces the formation of chloramines and, therefore, irritation. The result is a disinfected and safe pool with much less active chlorine in the water.
Are these products safe for babies and very young children?
Yes. All three products are formulated without aluminum sulfate, metallic compounds, or synthetic chemicals that could accumulate in the water or be absorbed through the skin. By improving water balance, they also reduce the concentration of chloramines, which are the main cause of skin irritation in younger children. They are the most suitable option for family pools with babies or children of daily bathing age.
Are the pH raiser and alkalinity raiser the same?
No, although they are related. Total alkalinity acts as a pH buffer: when correctly adjusted (80-120 ppm), the pH remains stable. The pH raiser, on the other hand, directly corrects the pH value when it is below the optimal range (7.2-7.4). Therefore, you should always adjust alkalinity first and then pH, in that order, to achieve a lasting balance.
Can I use these products with any disinfection system?
Yes. All three products are compatible with all common disinfection systems: chlorine tablets or liquid, salt electrolysis, bromine, and UV systems. They do not interfere with any of them or modify their effectiveness. In fact, by optimizing pH and alkalinity, they enhance the action of any disinfection system you are using.
How often do I need to use the natural flocculant?
For preventive maintenance, the ideal frequency is every 15 days during the bathing season. After heavy rains, very intensive use, or when the water shows visible turbidity, it should be applied as needed without waiting for the usual cycle. The powder format with scoop dosing (2 scoops per 10 m³) makes the process very simple and without risk of overdosing.
Can atopic skin improve with the use of these products?
The use of these products is not a medical treatment for atopic dermatitis, but it can significantly reduce factors triggering flare-ups related to swimming in a pool. By eliminating aluminum sulfate from the water, stabilizing the pH, and reducing chloramines, the water becomes much less irritating for atopic skin. Many families with atopic children report a notable improvement in bath tolerance after incorporating these products into their maintenance routine.
