What is Trichlor TCCA and how it works?
What Is Trichlor or TCCA?
Trichlor—or“Trichloro-S-Triazinetrione”if you’re feeling adventurous—is a type of chlorine that’s commonly used in swimming pools.
Comes in tablet (most common) or granular form
Both forms have a pH of around 3
Contains around 90% active chlorine
Contains pool stabilizer (cyanuric acid)
How Does Trichlor Chlorine Work?
Trichlor sanitizes your pool water the same way other chlorine types do.
Once dissolved and released into the water, it turns into hydrochloric acid that combines with microorganisms and other nasties, breaking down their cell walls and disrupting their chemical structures.
This “combined chlorine” is also referred to as chloramines, and chloramines are pretty harmless until they build up too much in the water — but that’s where regularly shocking your pool comes in.
The Advantage of using Trichlor
It’s very strong, so you’ll need to use less product to reach the required level of free chlorine in your pool, which is around 3 parts per million (ppm).
It’s “set and forget” since they’re slow-dissolving tablets, meaning you don’t have to manually add chlorine to your pool everyday unlike when using liquid chlorine.
It’s fairly easy to transport as it comes in varying sizes of containers. Buying them locally isn’t too difficult, and shipping costs are reasonable too.
It has a long shelf life, so you can stock up and get your chlorine tablets from the same batch season after season, without having to worry about potency issues.
It’s very affordable. In fact, it’s one of the cheapest types of chlorine you can buy after sodium hypochlorite (liquid chlorine), alongside Calcium Hypochlorite.
AQUACLEAR TCCA (Trichlor) Tablet Usage Guide
1. Purpose
AQUACLEAR TCCA tablets are a stabilized chlorine disinfectant used to:
✔ Kill bacteria, algae, and other contaminants.
✔ Provide long-lasting chlorination (slow-dissolving).
✔ Help maintain pool hygiene with added Cyanuric acid (CYA) for UV protection.
2. Application Methods
Floating Dispenser: Place 1–3 tablets in a chlorine floater (adjust based on pool size).
Skimmer Basket: Add 1–2 tablets directly into the skimmer (only if pump runs 24/7).
Automatic Chlorinator: Use with an inline feeder for controlled release.
3. Dosage Recommendations
| Pool Size (Gallons) | TCCA Tablets (200g each) | Frequency |
| 10,000 | 1–2 tablets | Every 5–7 days |
| 20,000 | 2–3 tablets | Every 5–7 days |
| 30,000+ | 3–4 tablets | Weekly or as needed |
⚠ Note:
Do not exceed 5 ppm free chlorine (test regularly).
Do not mix with other chemicals (especially calcium hypochlorite or non-stabilized chlorine).
4. Safety & Handling
✔ Wear gloves when handling tablets.
✔ Store in a cool, dry place (away from sunlight and moisture).
✔ Keep away from children and pets (TCCA is highly concentrated).
❌ Never throw tablets directly into the pool (can bleach liners or damage surfaces).
5. Monitoring & Adjustments
Test free chlorine (2–4 ppm) and pH (7.4–7.6) regularly.
If chlorine is too high, reduce tablet count or remove floater temporarily.
If cyanuric acid (CYA) exceeds 50 ppm, switch to unstabilized chlorine temporarily.
