Before you can reopen the pool for summer swims, you need to clean out the debris and restore the water to its proper chemical balance.
Clean the components of the filter
Add 5 liter of Acti Clean Filtre into the sand filter. Leave it at least for 1 hour and 30 minutes.
If you have another kind of filter system, place the components into a container filled with a solution consisting of up to 10% of a filter scale remover product (1 liter for 10 liters of water).
pH adjustment
Analyse the total alkali strength (TAS) and TH to determine the ideal pH and then adjust it with pH Plus or Minus. Adjust the TAS and TH where applicable.
Shock treatment
Use Acti Shock, 150 g per 10 m3. After dissolution in warm water, place them directly in the pool in front of the discharge nozzles and make sure that no swimmers are in the water.
Maintenance treatment
Acti Long Tab, 1 tablet per 25 m3 every 7 to 10 days.
If you have a sand filter: Acti multi-purpose tablets, 1 tablet per 25 m3 every 5 to 8 days.
Scale remover treatment
Apply Acti Anti-Kalk over the tank with a watering can, 1 liter per 20 m3.
Flocculation in sand filters
If you have a sand filter, use Acti Floc Bag 1 per 25 m3 in the skimmer or pre-filter.
Transparency
Use an anti-algaecide twelve hours after the chlorine treatment.
