Swimming Pool Chlorine Tablets — Professional Grade Sanitization
Maintaining safe, crystal-clear pool water requires reliable, consistent disinfection. Swimming pool chlorine tablets from Everglory Industrial deliver controlled-release sanitization that keeps free chlorine levels stable, prevents algae growth, and protects swimmers from waterborne pathogens. Our pool chlorine tablets are trusted by pool service companies, hotels, municipalities, and distributors in the world.
Why Choose Chlorine Tablets for Pool Sanitization?
Unlike liquid chlorine or granular chlorine, tablet formulations provide a slow, consistent release of active chlorine over several days. This eliminates the peaks and valleys in chlorine levels that occur with manual dosing, ensuring continuous protection with less maintenance.
Key advantages of tablet form for pools:
- Consistent dosing: Slow dissolution maintains stable 1–3 ppm free chlorine residual
- Reduced maintenance: A single 200g tablet can treat a residential pool for 5–7 days
- Safer handling: Solid tablets eliminate splash risk associated with liquid chlorine
- Cost-effective: Lower transportation and storage costs vs. liquid chlorine (which is 90% water)
- UV protection: TCCA tablets contain cyanuric acid stabilizer, extending chlorine life in outdoor pools
Recommended Pool Chlorine Tablet Formulations
TCCA 90 Tablets — Best for Outdoor Pools
For outdoor swimming pools exposed to sunlight, TCCA (trichloroisocyanuric acid) 90% tablets are the industry standard. The built-in cyanuric acid stabilizer protects chlorine from UV degradation, which can destroy up to 90% of unstabilized chlorine within 2 hours of direct sunlight. TCCA tablets maintain effective disinfection for 5–7 days per application.
| Specification | Value |
|---|---|
| Available Chlorine | ≥ 90% |
| Tablet Sizes | 20g, 50g, 100g, 200g |
| pH (1% solution) | 2.7 – 3.3 (acidic — lowers pool pH) |
| Dissolution Time (200g) | 5–7 days in standard chlorinator |
| Cyanuric Acid Content | ~55% by weight |
| Recommended CYA Level | 30–50 ppm (do not exceed 100 ppm) |
Calcium Hypochlorite Tablets — Best for Indoor Pools
For indoor pools, spas, and applications where cyanuric acid buildup is a concern, calcium hypochlorite tablets (65–70% available chlorine) provide powerful sanitization without stabilizer. Cal Hypo has a higher pH (10–11), which helps raise pool pH — beneficial in pools that tend to run acidic.
Dosing Guidelines for Pool Chlorine Tablets
Proper dosing depends on pool volume, water temperature, bather load, and sunlight exposure. The following table provides general guidelines for residential and commercial pools:
| Pool Volume | Tablet Size | Tablets Needed | Frequency |
|---|---|---|---|
| Residential (10,000–20,000 gal) | 200g (3-inch) | 1–2 tablets | Every 5–7 days |
| Medium Pool (20,000–50,000 gal) | 200g (3-inch) | 2–4 tablets | Every 5–7 days |
| Commercial Pool (50,000+ gal) | 200g (3-inch) | 4+ tablets | Every 3–5 days |
| Spa/Hot Tub (500–1,000 gal) | 20g | 1–2 tablets | Every 2–3 days |
Note: Always test and adjust free chlorine to maintain 1–3 ppm. Monitor pH (7.2–7.6) and cyanuric acid levels (30–50 ppm outdoor) regularly.
Application Methods
Floating Dispensers: The simplest method for residential pools. Place tablets in a floating chlorinator and allow it to disperse chlorine as it dissolves. Ensure the dispenser does not rest against pool surfaces, as concentrated chlorine can cause bleaching.
Automatic Chlorinators: In-line or off-line chlorinators are recommended for commercial pools and professional installations. These devices control the dissolution rate by adjusting water flow, providing precise chlorine dosing.
Skimmer Baskets: While convenient, placing tablets directly in the skimmer is not recommended for pools with variable-speed pumps running at low speeds, as concentrated chlorine can damage pump components over time.

Frequently Asked Questions
Q: Can I use TCCA tablets in an indoor pool?
While possible, TCCA tablets add cyanuric acid to the water, which serves no purpose indoors (no UV exposure) and can accumulate to problematic levels. For indoor pools, calcium hypochlorite tablets are recommended. If CYA exceeds 50 ppm indoors, partial water replacement is necessary.
Q: How long do pool chlorine tablets last in storage?
When stored in a cool, dry, well-ventilated area in sealed containers, TCCA tablets retain full potency for 24 months. Calcium hypochlorite tablets have a shelf life of 12–18 months. Always check the manufacturing date and store away from heat and moisture.
Q: Can I mix different types of chlorine tablets?
No. Never mix TCCA and calcium hypochlorite tablets in the same chlorinator or dispenser. Mixing different chlorine compounds can cause dangerous chemical reactions, including heat generation and toxic gas release. Always fully clean and dry equipment before switching chlorine types.
Q: Do you offer individually wrapped tablets?
Yes. For retail and private label customers, we offer individually foil-wrapped tablets in various sizes. This improves shelf life, prevents moisture absorption, and provides convenient single-use dosing. MOQ for individually wrapped tablets is typically 3 tons.
Q: What is the lead time for bulk orders?
Standard production lead time is 15–20 days for full container loads. For stock items, we can ship within 7–10 days. We maintain inventory of popular sizes (200g TCCA, 200g Cal Hypo) for faster turnaround. Contact us for current production schedules.
