As temperatures in South America rise, summer is approaching. Swimming pools are about to become a popular place for people to relax and unwind.
From Brazil and Argentina to Chile, Colombia, and Peru, this is a crucial moment for pool chemical distributors to ensure sufficient inventory and cope with the peak demand.
In most parts of South America, the swimming peak lasts from November to March of the following year. During this period, the sales of swimming pool chemicals will increase by more than 50% compared with winter. To seize this opportunity, pool chemical dealers must focus on stockpiling essential chemicals. This article will focus on introducing which chemicals South American distributors should stock up on before the peak season arrives.
Swimming Pool Disinfectant
Pool Disinfectant is the most indispensable chemical in pool maintenance. It can not only ensure the cleanliness and hygiene of the swimming pool, but also guarantee the health of the swimmers. The high temperatures in summer and the frequent use of swimming pools have increased the necessity and frequency of pool disinfection. There are roughly three types of chlorine disinfectants commonly used in swimming pools: trichloroisocyanuric acid, sodium dichloroisocyanurate, and calcium hypochlorite.
Long-acting chlorine tablets, Cloro em Pastilhas, Cloro para Piscina 90%, Pastilhas de Cloro Estabilizado, TCCA 90%, Tricloro 90%
In terms of swimming pool disinfection, trichloroisocyanuric acid (TCCA) has always been the best-selling product in Latin America. TCCA is renowned for its high chlorine content (90%), slow and stable release, and broad-spectrum bactericidal effect, effectively eliminating bacteria, viruses, and algae in swimming pool water.
TCCA is particularly favored by residential swimming pool owners and service companies due to its convenience and safety. TCCA typically offers 200-gram tablets (suitable for large swimming pools), 20-gram tablets (suitable for small swimming pools or spas), as well as granules and powders (for convenient and flexible use).
The advantages of TCCA
Provide persistent chlorine release.
Reduce the frequency of manual chlorination.
Stabilize the chlorine content under strong sunlight.
It is very suitable for the typical warm and sunny climate of South American summers.
Dealer's Tip
We offer trichloroisocyanuric acid (TCCA) in various packaging specifications, such as 1kg, 5kg and 50kg drums, to attract both household users and professional maintenance companies. Many distributors in Brazil and Argentina prefer tablets because they are easy to handle and familiar to consumers.
Instant chlorine used for shock treatment. Stabilized chlorine granules, Fast Chlorine, Fast-Acting Chlorine, Dicloro 60%
Sodium dichloroisocyanurate (SDIC) is another potent and widely used chlorine disinfectant, typically employed for shock chlorination and rapid disinfection. Unlike TCCA, SDIC dissolves quickly in water and releases chlorine almost immediately, making it the preferred product for frequently used or post-rain treatment swimming pools.
Why SDIC is crucial in swimming pools:
Fast-dissolving formula, achieving immediate disinfection effect.
High effective chlorine (56-60%) ensures powerful disinfection.
It leaves very little residue and is suitable for all types of swimming pools and water systems.
It can also be used for disinfecting drinking water in emergency situations or rural areas.
In the South American market, SDIC's powder and granular products are particularly popular because they are easy to measure and add. Some distributors also offer SDIC in effervescent tablet form, a convenient dosage form that is highly favored by households and hotels seeking rapid and clean water treatment.
Dealer's Tip
Promote SDIC as "shock treatment" chlorine and TCCA as "maintenance chlorine". This dual-product strategy helps to increase repeat purchase rates and customer loyalty.
Calcium hypochlorite, commonly known as Cal Hypo, has been used as a reliable water disinfectant for decades. With an effective chlorine content of 65%-70%, it possesses strong oxidizing properties, killing bacteria, fungi, and algae. A major advantage of Cal Hypo is that it does not require the addition of cyanuric acid to the pool, thus avoiding the common chlorine lock problem caused by over-stabilization. However, for outdoor pools, special care must be taken to prevent chlorine loss due to sunlight exposure, unlike adding cyanuric acid to stabilize the pool.
Why Cal Hypo is so important to distributors:
Suitable for commercial pools, resorts, and public facilities.
Strong oxidizing power for rapid disinfection.
Lower cost per unit of active chlorine compared to liquid sodium hypochlorite.
Optimal choice for shock treatment or regular dosage.
However, due to its high reactivity, Cal Hypo must be stored carefully. Distributors should adhere to strict safety and packaging standards, especially in the warm and humid climate of South America. Using lined plastic drums can extend shelf life and reduce moisture absorption.
Distributor Tip:
Combine Cal Hypo promotions with professional pool management products (such as automated dosing systems or pre-dissolving containers) and educate customers on how to use them safely and effectively.
In hot and humid seasons, algae growth is one of the most common problems in swimming pools in South America. Once algae start to multiply, it will not only make the water turn green or turbid, but also breed bacteria. Therefore, Algaecides are indispensable preventive and maintenance products in the product catalog of every distributor.
The reasons for the high demand for algaecides:
It can prevent algae growth even at high temperatures.
Compatible with most chlorine-containing disinfectants.
It helps keep the water clear throughout the season.
Reduce chlorine consumption by improving water balance.
There are mainly two types of algaecides: copper-based algaecides and quaternary ammonium salt algaecides. Copper-based algaecides are effective against severe algal infections, while non-foaming quaternary ammonium salt algaecides are more suitable for daily maintenance, especially in swimming pools with strong circulation systems.
In warm weather, after a large number of swimmers have swam or after a heavy rain, the water body is prone to become cloudy. At this time, the swimming pool should be subjected to impact and clarification treatment. Clarification is usually carried out after the impact step. Clarifiers can help purify turbid water by gathering small particles together, so that it can be filtered or sucked out.
Cyanuric Acid acts as a sunscreen for chlorine. It binds to free chlorine molecules, reducing UV degradation and prolonging disinfection effectiveness. Unstabilized pools exposed to strong sunlight can lose up to 90% of their free chlorine within two hours.
Recommended Concentration:
30–50 ppm in most pool systems.
Packaging Preferences in South America:
Brazil: 25 kg and 50 kg fiber or plastic drums
Argentina and Chile: 1 kg and 5 kg retail packages for the consumer market; 25 kg packages for distributors
Colombia and Peru: Typically imported as a bulk powder and repackaged locally
Market Insight:
South American distributors report strong demand for cyanuric acid from October to January as pool maintenance companies prepare for peak summer usage.
As summer approaches, competition in the South American pool chemical market intensifies. Distributors who prepare ahead of time will gain a significant advantage in terms of price, availability, and customer satisfaction. Six key products—trichloroisocyanuric acid (TCCA), SDIC, Cal Hypo, algaecides, clarifiers, and cyanuric acid—are the foundation of a successful inventory strategy.
