Chlorine tablets for the pool – choose the right type of chlorine
Those looking for chlorine tablets for their pool often want a practical way to maintain the correct disinfection level. However, terms such as tablets, sticks, and granules are sometimes used loosely. The products may contain different active ingredients and be suitable for different dosing systems. Therefore, choose based on the ingredients, pool type, and equipment—not just the form.
What makes chlorine tablets different from other chlorine products?
Chlorine products can be stabilized or unstabilized and sold as tablets, sticks, granules, or liquids. Their properties, intended use, and dosing equipment requirements vary. For example, PPG Deluxe Calhyp-O chlorine sticks (/products/ppg-deluxe-calhyp-o-klorsticks-300-g-4-8-kg) are just sticks, not necessarily a direct replacement for any stabilized tablet. Always check the product's active ingredient and instructions for use.
Choose based on your pool and dosing system
A pool with manual dosing has different requirements than one with automatic chlorine dosing. If a dosing system is already in place, check that it is compatible with the products approved by the manufacturer. Do not choose a type of chlorine simply because it physically fits in a container. It is also important to follow current recommendations for water balance and testing.
Stabilized or unstabilized chlorine
Some chlorine products contain a stabilizer, while others do not. In outdoor pools, a stabilizer can affect how chlorine behaves in sunlight, but excessively high levels can also be problematic. Use a testing method suitable for the pool in question and choose a product based on previous water treatment and the manufacturer's instructions.
Safe handling is essential
Never mix different chlorine products together or with acids.
Do not use a container previously used for a different type of chemical without explicit approval.
Follow the product label and safety data sheet for dosing and protection.
Store original packaging in a cool, dry place, out of reach of children.
Check the disinfection level and pH with a reliable water analysis test before swimming.
Frequently asked questions
Are chlorine tablets and chlorine sticks the same thing?
No, not necessarily. The form does not tell you everything about the active ingredient or which dosing systems the product is suitable for.
Can I switch from tablets to liquid chlorine?
This may require different dosing equipment and a change in maintenance routine. Liquid chlorine (/products/klor-flytande-20l) should be treated as a different type of product and handled according to its instructions.
How many tablets do I need?
This depends on the pool's water volume, the specific product, and the water levels. Follow the label instead of general dosing advice.
