Slow-Dissolving Tablets for All-in-One Chlorine Care
Zodiac All-in-One TriChlor Pool Tablets are slow-dissolving chlorine tablets for floaters, feeders and skimmer baskets. They help control bacteria, viruses and algae, supporting cleaner pool water with ongoing sanitising plus added algae and clarity support.
Each 200g tablet provides a pre-measured chlorine dose for pools up to 20,000 litres. With built-in algaecide, clarifier, stabiliser and UV blockout, these tablets are a practical option for weekly maintenance, holidays or winter chlorine support.
Features & Benefits
- All-in-one tablet formula: Combines chlorine, built-in algaecide, clarifier and stabiliser / UV blockout support in one tablet.
- Controls bacteria, viruses and algae: Helps maintain sanitised swimming pool water for regular pool use.
- Pre-measured 200g tablets: Easy to dose, with 1 tablet suitable for up to 20,000 litres.

- Individually wrapped tablets: Supports safer, more comfortable handling.
- Useful maintenance option: Ideal for once-a-week application, holidays or winter use as an alternative to salt chlorination.
How to Use
- Test pool water and confirm chlorine and cyanuric acid levels are suitable before use.
- Place 1 tablet per 20,000 litres into a floating dispenser, automatic tablet dispensing device or skimmer basket.
- Run the pool pump as part of normal circulation and retest water regularly to maintain the correct chlorine level.
Dosage & Coverage
- Standard dose: 1 tablet per 20,000 litres.
- Pack size: 10 x 200g tablets per 2kg pack.
Important Usage Information
- Tablet dissolving rate will vary depending on water flow and temperature.
- Always check cyanuric acid levels before use. If levels are above 100ppm, consider using a non-stabilised chlorine.
- For pools with ORP probes or automated chlorinator controls, cyanuric acid should be kept low, as high stabiliser levels can affect probe performance.
- Trichlor has a low pH of 2.5–3, so pH and Total Alkalinity should be tested regularly during use.
- Do not place tablets directly on pool surfaces.
- Always follow the product label directions and safety instructions.
Recommended pool levels: free chlorine 2-4ppm, combined chlorine less than 0.2ppm, and cyanuric acid 10-50ppm. For ORP/probe systems, cyanuric acid should be kept under 20ppm.

Frequently Asked Questions
Do All-in-One TriChlor tablets need to be pre-dissolved?
No. The 200g tablets do not need to be pre-dissolved. Place the tablet in a floating dispenser, automatic tablet feeder or skimmer basket so it can dissolve gradually through normal pool circulation.
Why does the tablet dissolve faster or slower at different times?
The dissolving rate depends on water flow and water temperature. Tablets usually dissolve faster with stronger circulation or warmer water, and more slowly in cooler water or lower-flow dispensers.
Will these tablets increase calcium hardness?
No. Trichlor tablets do not add calcium hardness to the pool water, making them different from calcium-based chlorine products.
Why should pH and Total Alkalinity be checked during use?
Trichlor has a low pH of around 2.5–3. Regular use can place downward pressure on pH and Total Alkalinity, so these levels should be tested and adjusted as part of normal water balance maintenance.
Why is cyanuric acid important with All-in-One TriChlor tablets?
These tablets are stabilised, so they add cyanuric acid to the water. The right stabiliser level helps chlorine last longer, but high cyanuric acid can reduce chlorine performance. If cyanuric acid is above 100ppm, a non-stabilised chlorine such as Zodiac Pool Chlorine may be more suitable.
Are these tablets suitable for pools with ORP probes or automated controls?
They can be used with care, but cyanuric acid should be kept low for pools using ORP probes or automated chlorinator controls. High stabiliser levels can affect probe readings and chlorine control performance.
How are these different from standard Stabilised Pool Chlorine Tablets?
Both products are slow-dissolving Trichlor tablets with stabiliser support and UV blockout. The All-in-One TriChlor Pool Tablets also include built-in algaecide and clarifier, giving extra maintenance support in the same tablet format.
Can I place the tablets directly in the pool?
No. These tablets should be used in a floating dispenser, automatic tablet dispensing device or skimmer basket. Placing concentrated Trichlor tablets directly on pool surfaces can cause localised bleaching or surface damage.
