TCCA Tablets — Stabilized 90% Chlorine Tablets for Outdoor Pools

TCCA tablets are pre-measured, slow-eroding solid chlorine sanitizers that combine a high 90% minimum available chlorine content with built-in cyanuric acid stabilization, making them the most efficient tablet choice for outdoor pools exposed to sunlight. Each tablet dissolves at a controlled rate, releasing chlorine while depositing a stabilizer shield that protects the free chlorine residual from rapid UV degradation. Everglory Industrial manufactures and exports premium-grade TCCA tablets in two standard sizes — 3-inch (200g) slow-dissolving tablets for large pools and automatic feeders, and 1-inch (20g) faster-dissolving tablets for small pools and spas — supplied in UN 2468 certified plastic drums to B2B buyers across 60+ countries.

TCCA Tablet Sizes & Selection

Choosing the correct tablet size is the first step to efficient pool chlorination. The two standard TCCA tablets sizes cover the full range of pool volumes and dosing equipment:

For pools above 50,000 liters, the 3-inch 200g tablet is the economical choice: fewer tablets are handled, dosing intervals extend to a full week, and the tablet fits all standard erosion feeders and skimmer baskets. For pools below 30,000 liters, spas, and hot tubs, the 1-inch 20g tablet provides finer dose control and avoids over-chlorination from an oversized 200g tablet eroding too slowly. Pool service companies typically stock both sizes to serve mixed client portfolios from a single drum shipment.

How to Use TCCA Tablets

TCCA tablets are designed for low-maintenance, equipment-based dosing. Four application methods cover every pool configuration:

• Skimmer basket method: Place 200g tablets directly into the skimmer basket. Circulating water erodes the tablet and returns stabilized chlorine to the pool through the jets. Tip: run the pump for at least 4-6 hours daily so dissolved chlorine is distributed rather than concentrating in the skimmer and pipework.
• Floating dispenser method: Load 1-3 tablets into a floating dispenser and adjust the bottom vents to control the erosion rate. This method suits pools without skimmers or where feeder installation is impractical. Tip: remove the dispenser while the pool is in heavy use to avoid concentrated chlorine contact with bathers.
• Erosion feeder method: Commercial pools and hotels use dedicated erosion feeders, where pressurized water passes through a stack of 200g tablets for precise, automated chlorination. Tip: trichlor is acidic — feeders should be dedicated to TCCA only and the pool pH monitored and adjusted upward as needed.
• Inline chlorinator method: Inline chlorinators plumbed into the return line offer the most consistent dosing for large private pools, dissolving tablets at a set flow rate. Tip: never mix leftover calcium hypochlorite or other chemicals in the same chlorinator — refill with TCCA tablets only, after rinsing the chamber.

Safety note: Never mix TCCA tablets with calcium hypochlorite or any other pool chemical — dangerous reactions can occur. Store and dose trichlor products separately, and always handle tablets with gloves and eye protection.

TCCA Tablets Dosing Guide

The following guide provides typical dosing for 3-inch (200g) TCCA tablets in outdoor pools, targeting a 1-3 mg/L free chlorine residual. Actual demand varies with bather load, temperature, and rainfall — always confirm with a test kit:

Advantages of TCCA Tablets for Outdoor Pools

• UV stabilization reduces chlorine waste: the cyanuric acid released with each tablet shields free chlorine from sunlight destruction, cutting chlorine consumption by up to two-thirds in outdoor pools compared with unstabilized sanitizers.
• Week-long dosing intervals: a 200g tablet erodes for 5-7 days, reducing labor and site visits — a decisive cost advantage for pool service companies maintaining multiple client pools.
• No calcium buildup: TCCA adds no calcium to the water, avoiding rising calcium hardness and scale formation on tile, heaters, and heat exchangers.
• Pre-measured accuracy: at 90% available chlorine, each tablet delivers a known chlorine dose with no weighing, no dust, and no handling exposure during dosing.
• Feeder compatible: the 3-inch tablet is the global standard size for erosion feeders and inline chlorinators, enabling fully automated dosing for commercial facilities.

Managing Cyanuric Acid Levels

Because every TCCA tablet adds cyanuric acid to the water, responsible dosing includes routine stabilizer management. Test cyanuric acid (CYA) monthly with a test kit or test strips during the swimming season. The ideal working range is 30-50 ppm — enough stabilizer to protect the chlorine, but low enough for chlorine to work effectively. When CYA exceeds 100 ppm, chlorine becomes over-stabilized and disinfection slows; correct by partially draining the pool and refilling with fresh water to dilute the stabilizer concentration, then resume tablet dosing. Indoor pools should not use stabilized tablets on a continuous basis, since UV degradation does not occur indoors and CYA accumulates without benefit.

Packaging & Storage

Everglory Industrial packs TCCA tablets exclusively in UN 2468 certified plastic drums with inner liners for safe international transport. Standard drum sizes and approximate tablet counts per drum are listed below; custom drum weights are available for OEM clients:

Store TCCA tablets in the original sealed plastic drum in a cool, dry, well-ventilated area away from direct sunlight, heat sources, moisture, acids, ammonia, and combustible materials. Keep drums away from calcium hypochlorite and other chlorinating products at all times. Shelf life is 24 months from production when stored correctly. Reseal the drum tightly after each opening, as absorbed moisture accelerates tablet degradation and chlorine loss.
