Chlorine Tablets for Your Pool
Out of all the swimming pool chemicals available, chlorine is one of the most essential for treating your pool water. Affordable and easy to use, chlorine tablets are vital for keeping your pool in good condition.
Perfect to add to a skimmer basket, pool chlorine feeder, or a floating container, chlorine tablets act by slowly dispersing through the water over a period of 3-5 days to kill harmful bacteria.
Keep in mind the following:
- Chlorine levels for pools need to be between 1-3ppm.
- Chlorine levels for hot tubs and spas need to be between 3-5ppm.
- Keep an eye on chlorine levels by using water testing equipment strips.
For more information on how pool chemistry works, take a look at our guide on what chemicals you need for pool and hot tub maintenance.
Shock Treatments for Your Pool
Due to the slow release of a chlorine tablet, a shock dose may be necessary to more rapidly establish chlorine levels. We suggest incorporating regular shock or oxidising treatments to your weekly or fortnightly pool maintenance routine.
Chlorine Granules for Your Pool
Chlorine granules are also available as a method of cleaning your pool, designed to dissipate through the water at a much faster pace than tablets.
We highly recommend using chlorine tablets for the vast majority of swimming pools and faster acting granules for hot tubs.
Explore our guide to learn more about how chlorine tablets and granules work to discover which will be better for your pool.
Chlorine Tablets Shelf-Life
When stored correctly, chlorine tablets have a long shelf life of around 3-5 years. Ensure you make the most out of this product by keeping them in a cool, dry place that isn’t exposed to direct sunlight.
Chlorine Tablet Sizes
If you are using a chlorine feeder, you may need to use smaller 20g chlorine tablets. Our larger chlorine tablets are 200g and pair well with floating dispensers.
Stabilising vs Multifunctional Chlorine Tablets
Stabilised and multifunctional chlorine tablets work similarly in that they disinfect pool water over a longer period of time than unstabilised tablets. The main difference is that multifunctional tablets combine the function of several different products.
For example, our 20g Multifunctional Chlorine Tablets contain stabilised chlorine, a clarifier and algaecide. Standard stabilising tablets are highly effective, but if your pool requires a deeper clean, then we recommend using multifunctional tablets.
