Chlorine pool tablets made from trichloroisocyanuric acid (TCCA) at 90% are a slow-dissolving solid disinfectant product, formulated for the continuous maintenance of sanitary water quality in high-intensity professional aquatic installations. The high concentration of active chlorine guarantees high performance per tablet, while the integrated isocyanurate acts as a UV stabiliser, preserving product efficacy in pools exposed to solar radiation without the need for external stabiliser additives. The progressive dosing prevents the concentration peaks typical of granular or liquid formats, protecting the installation materials and facilitating analytical control of the water.
Chlorine tablets 90% is formulated and manufactured by Detervic / Instaquim, with technical support for distributors and professional operators. The product has bactericidal action regulated in accordance with current biocide regulations — verify applicable registration — and its technical sheet is available for authorised customers and distributors.

Prolonged disinfectant action — slow and controlled release of active chlorine maintains stable levels for longer, reducing the frequency of intervention in high-demand installations.
High concentration of active chlorine (90%) — higher performance per tablet compared to lower-strength formulations, with direct impact on treatment cost.
Integrated UV stabilisation — isocyanurate protects chlorine against ultraviolet radiation degradation, especially effective in outdoor pools without the need for additional stabiliser.
Formula without unnecessary additives — phosphate-free, no artificial colours, no fragrance, no EDTA, no NTA, no alcohol; clean composition that does not interfere with water analysis and does not favour algal development.
Solid format with precise dosing — easy to store, handle and dose; avoids the risks associated with corrosive liquid formats and the concentration peaks of granular products.
Compatible with other water treatment products — integrates with algaecides, flocculants, scale inhibitors and stabilisers without compromising the overall effectiveness of water treatment.
Product with regulated bactericidal action — in compliance with current biocide regulations; verify applicable registration in each market.
Main applications
Routine maintenance of community and residential pools: continuous monitoring of free chlorine in installations with daily use and high bather load, ensuring clear and sanitised water without frequent interventions.
Sports and municipal facilities: maintenance chlorination and shock chlorination in indoor and outdoor pools with strict sanitary requirements defined by regulations.
Hotels, tourist resorts and water parks: daily monitoring of pH and chlorine levels in installations where water quality is an auditable service standard.
Spas, thermal centres, wellness facilities and therapeutic pools: water treatment in hydrotherapy installations and geriatric care where the water must remain permanently sanitised with controlled chlorine levels.
Pool maintenance companies: benchmark product for professional operators managing multiple installations and requiring high performance with ease of dosing.
Recommended sectors
HoReCa — hotels, tourist resorts and establishments with outdoor or indoor pools for seasonal or permanent use; chlorine level control forms part of service quality standards.
Sports and leisure facilities — municipal pools, sports clubs and water parks where shock chlorination and preventive maintenance are mandatory under sanitary regulations.
Maintenance and service companies — professional operators managing multiple installations and requiring high-performance products, ease of dosing and direct technical support from the manufacturer.
Healthcare and geriatric care — therapeutic pools and hydrotherapy installations where free chlorine control and water hygiene are non-negotiable sanitary requirements.
Indicative instructions for use
01
Analyse the pool water before treatment: measure free chlorine, pH and alkalinity values to establish the baseline.
02
Adjust water pH between 7.2 and 7.6 before adding tablets to ensure maximum disinfectant efficacy of active chlorine.
03
Place tablets in a floating dispenser, skimmer or automatic chlorinator. Never directly into the pool basin or in contact with other chemical products.
04
Dose according to water volume, temperature, solar radiation and bather load. Consult the product technical sheet for recommended quantities.
05
For shock chlorination, increase dosage according to manufacturer instructions, preferably in the absence of bathers and with the filtration system running. Verify levels before allowing use of the facility.
Dosages, contact times and specific recommendations are available in the product technical sheet.
