Start with the chemical your equipment is designed to use, then check recent pool readings and the exact supplied specification. TCCA tablets introduce cyanuric acid stabiliser; sodium hypochlorite is unstabilised liquid chlorine. Neither format replaces routine water testing. Gotech offers 200 g tablets in 1 kg packs or 25 kg drums. For liquid chlorine, request the litres needed; strength, container size, price and delivery are confirmed in the quotation.
Scope: this is a purchasing comparison, revised on 5 September 2026. Product labels, equipment instructions and your pool's operating requirements determine product use and dosing.
The two product formats
Chlorine tablets on this site are slow-dissolving TCCA (trichlor) tablets. Confirm that the proposed tablet and its 200 g size match your dispenser's instructions. A feeder being suitable for one chlorine product does not establish compatibility with another.
Liquid chlorine is sodium hypochlorite solution. Confirm the specified concentration against the dosing pump, tank and operating settings. Household bleach and commercial pool products should not be assumed to have the same formulation or instructions.
What to compare
On a smaller screen, scroll the table sideways to compare both products. With a keyboard, focus the table and use the arrow keys.
| Check | TCCA tablets | Liquid chlorine |
|---|---|---|
| Request format | 1 kg pack (5 × 200 g tablets) or 25 kg drum | Litres required; supplied container size to confirm |
| Strength | Confirm the available-chlorine specification of the quoted product | Confirm available chlorine and its units, such as g/L; a percentage needs its stated measurement basis |
| Equipment | Check the exact product and tablet size against dispenser instructions | Check the solution against pump, tank and dosing instructions |
| Water results | Include cyanuric acid, free chlorine, pH and alkalinity readings | Include current free chlorine, pH, alkalinity and existing product details |
| Storage and use | Confirm label storage instructions, usable shelf life and planned consumption | Confirm product age, storage conditions and expected consumption |
| Cost comparison | Quoted pack price, quantity, delivery and any equipment or treatment changes | Quoted litres, supplied strength, delivery and any equipment or treatment changes |
Compare quotations on the same stated specification and delivery basis. A drum price and a price per litre are not directly comparable. The lower pack price does not establish the lower cost for your pool.
Stabiliser and water results
Trichlor contains cyanuric acid. Its presence changes chlorine disinfection behaviour, so a chlorine reading alone is not enough to judge a product change. Sodium hypochlorite does not introduce cyanuric acid. Ask your operator to review the existing stabiliser result and treatment plan before changing supply. The CDC explains why stabilised chlorine requires different consideration.
For a Hong Kong licensed pool, follow its own licence and operating requirements. FEHD's published conditions require daily chlorine and pH testing and records; tablets or automatic dosing do not remove that duty. See Hong Kong pool licence requirements and the FEHD application guide.
pH and correction products
Trichlor is an acidic chlorine source and can affect pH and alkalinity. Assess correction requirements from measured water results and the operating procedure. Do not add acid or an alkalinity product simply because the pool uses tablets or liquid chlorine. The CDC's 2024 MAHC annex discusses water balance; it is US technical guidance, not a Hong Kong licence condition.
When requesting pH increaser, pH decreaser or alkalinity increaser, include the recent readings so each product can be reviewed in context.
Before requesting tablets
- Provide the dispenser model or its specified product and tablet size.
- Check the most recent cyanuric acid result with your operator.
- Choose 1 kg packs or 25 kg drums according to actual consumption and appropriate storage arrangements.
- Confirm that routine testing, records and replenishment checks remain assigned to the responsible operator.
Before requesting liquid chlorine
- Provide the current product name, labelled strength and concentration units.
- List the pump and tank details, usual consumption and litres requested.
- Ask for the proposed supplied concentration and container size in writing.
- Review the need for any equipment or operating-setting changes before accepting a substitute.
Hypochlorite can lose strength in storage. The rate depends on the product and conditions; confirm the supplier's shelf-life information rather than assuming a fixed period. The US EPA sodium hypochlorite profile describes the factors affecting stability.

Product documents and handling
Request the current safety data sheet (SDS), product data and label for the exact item being quoted. Follow those instructions for storage, protective equipment and use. Keep incompatible products separate and never mix chlorine products with each other or with acid. The CDC's pool chemical safety guidance explains these handling precautions.

Price, availability, minimum quantities and delivery terms need confirmation before an order.
Common purchasing questions
Are chlorine tablets or liquid chlorine cheaper?
Compare written quotations for the required supply, including the available-chlorine specification, quantity, delivery and any equipment or treatment changes. Pack price alone cannot establish which option costs less for your pool.
Can I use tablets and liquid chlorine in the same pool?
Have the responsible operator check the proposed products, equipment and operating procedure before using either or changing between them. Never mix chlorine products together, including in a container or feeder. A quotation is not an instruction to combine chemicals.
Do chlorine tablets expire?
Use the shelf-life, storage and expiry information for the actual supplied product. Ask for this with your quotation, especially when planning a larger purchase. Do not infer remaining strength or usable life from the product family name.
Do chlorine tablets lower pool pH?
Trichlor is an acidic chlorine source and can affect pH and alkalinity. Use current water tests and the operating procedure to decide whether any correction is needed. The choice of chlorine product alone does not determine a correction dose.
What should I confirm for an indoor pool?
Tell us that the pool is indoors and provide the present chemical specification, dosing equipment and recent water readings. Ask the operator to review stabiliser use and the proposed product before any change. Product names alone do not establish suitability.
