These MAREVA mini chlorine pebbles shock treatment for swimming pools - 5 kg - 125 g - 1002091 are the ultra-efficient curative solution for cleaning your pool. It is a shock treatment when your pool is particularly dirty and cloudy and sometimes even green: at the change of season after winter, during hot weather, after heavy use of the pool, after heavy rain or when the disinfection capacity is simply too low. Before opting for a constant bottom cleaner, you should first use this radical treatment with these high-performance 125 g effervescent and fast-melting chlorine pebbles. The filtering and cleaning action will then be complete after 12 hours, knowing that a 125 gram pebble treats 12.5 m3 of water. The result is no more bacteria or germs and a clear, blue colour again. The pebbles are compatible with all types of pools and liners, but it is important to avoid putting them in direct contact with the liner.
