Flocculants or Clarifiers are used generally once a month and when the pool water becomes cloudy which often happens when a green pool has been shock dosed.

Kibbled or Powdered Alum' is a great method for clarification of your swimming pool with the use of a sand filter.

Your filter sand can also affect pool water clarity so we suggest changing the sand at least every 3 years and also to use Surex Filter Cleanse to regularly dose your filter with to keep your sand working to its full efficiency.
