TCCA 90 Chlorine Tablet 10 kg

TCCA 90 Chlorine Tablet – High-Performance Pool Chlorine Tablets for Pool Disinfection

When people search for pool chlorine, this is the product that keeps a pool safe to swim in: Pearl Water's TCCA 90 Chlorine Tablets are premium-grade chlorine tablets for pool disinfection, sanitation, and microbial control. Made with high-purity Trichloroisocyanuric Acid — commonly known in the industry as trichlor tablets — this 10 kg pack delivers a stable, slow-dissolving release of active chlorine that keeps water clean, clear, and hygienic with less day-to-day dosing.

If you're comparing trichlor vs dichlor or wondering how TCCA differs from cal hypo, the short answer: trichlor tablets like this one are the most widely used chlorine tablets for pool maintenance because of their stability, slow-dissolve action, and lower handling risk compared to liquid chlorine. For a granular alternative that dissolves faster (useful for shock-dosing), see our TCCA 90 Chlorine Granules 10 kg — read more on liquid chlorine vs tablets and cal hypo vs trichlor in the FAQ section below.

Widely used in swimming pools, drinking water treatment systems, cooling towers, wastewater treatment plants, industrial water systems, and sanitation applications, TCCA 90 tablets effectively eliminate bacteria, viruses, algae, and fungi. This 10 kg pack is Pearl Water's standard bulk pool chlorine size — ideal for residential and mid-size commercial pools that need a reliable, low-maintenance chlorine supply. Need a larger volume?

How Much Chlorine to Add — Dosage & Usage Guide 

How much chlorine to add to pool water: As a general guide, dose TCCA 90 tablets at roughly 3–5 g per 10,000 litres of pool water per day, adjusted for bather load, temperature, and sunlight exposure — always confirm with a test kit rather than dosing on a fixed schedule.

How to use chlorine tablets in a pool: Place tablets in a floating chlorinator, skimmer basket, or an automatic pool chlorinator — never drop tablets directly onto the pool floor or add them by hand to concentrated water, as this can bleach liners and irritate skin.

Ideal chlorine level for pool: Maintain free chlorine (the active, sanitizing form) between 1–3 ppm for residential pools. If your test kit shows a gap between free chlorine vs total chlorine, that difference is "combined chlorine" (chloramines) — a sign it's time to shock the pool with our TCCA 90 Chlorine Granules, which dissolve faster than tablets and are better suited for shock dosing.

How long after adding chlorine can you swim: Wait until free chlorine reads below 5 ppm and pH is between 7.2–7.6 — typically 20–30 minutes after normal tablet dosing, though shock treatments may need several hours. Always verify with a test strip before swimming.

How often to add chlorine to pool: Check levels daily during peak swim season; a floating or in-line chlorinator loaded with these tablets can maintain levels automatically between manual checks.

Safety Information 

Is pool chlorine safe? Yes, when dosed correctly and used with a floating dispenser or chlorinator rather than added by hand. TCCA 90 is corrosive in concentrated form — always wear gloves, avoid inhaling dust, and store in a cool, dry, well-ventilated area away from direct sunlight.

Mixing pool chemicals — chlorine safety: Never mix TCCA 90 tablets with other pool chemicals (especially acids, cal hypo, or dichlor) directly — mixing dry chlorine products can cause a dangerous reaction and release chlorine gas. Add one product at a time and allow it to fully dissolve.
