The Acti 20g Small Chlorine Tablets are an essential way to make sure that your pool stays clear and hygienic. Designed to be used with a chemical floater - the tablets slowly releases the chlorine, algaecide and clarifier chemicals into the water to keep it consistently clean.

They are the easy and mess-free way to keep your pool clean, hygienic and looking clear. These tablets have multiple beneficial effects on your pool. They contain; chlorine, which kills bacteria and disinfects water; algaecide which kills and prevents the build-up of algae and clarifier, which can clog up your pool's filter.

Tablet chlorine has a long shelf life, so this easy to use tub container of 250 individually wrapped mini tablets is a cost-effective way to make sure you always have tablets to hand, as they are a crucial chemical for any home pool set up.


We recommend that 1 tablet should be used for every 350 gallons (1.6 m3) of pool water. These tablets will take approximately 2-3 days to dissolve but should be checked regularly.

Do not mix different chemical tablets in the same dispenser and ensure that if other chemicals have previously been used then the dispenser unit must be completely rinsed out before it is used again with this product. Never let tablets come into contact with the pool liner or components as bleaching and damage can occur. The tablets must be used in a floating dispenser or skimmer basket as they must not come into contact with pool liners or spas shells.

Safety Warnings: As with all chemical products, time should be taken carefully read through instructions and warnings. The label and container of 1kg Chlorine Granules is printed with guidelines and cautionary information.
