Frequently asked questions
Do both dispensers need to be used at the same time?
Not necessarily. The recommended dosage is 1 dispenser per 50 m³. The two units in the pack can be used according to the pool volume, or one can be kept to replace the first when it runs out.
How do I know when to replace a dispenser?
Once its contents have been used up, the dispenser will be floating on its side. It must then be removed and, if treatment needs to continue, replaced with another unit.
