10kg Certikin Swimfresh Multi-Functional Chlorine 200g Tablets

A new and improved version of stabilised chlorine tablets, these tablets still offer an easier way of maintaining chlorine levels and are applied via the skimmer, floating dispenser or chlorine feeder (trichlorinator).

They have a higher pH value, which reduces the amount of pH regulation you need to do and as well as being stabilised to reduce chlorine loss to sunlight they also contain clarifier and algaecides to help improve clarity and prevent algae formation.
