- Use one dispenser per 50 m³ of water.
- Cut off the tabs indicated on the packaging according to the pool volume.
- Place the dispenser in the water to provide automatic dosing throughout the winterization period.
- When the dispenser is floating on its side, its contents have run out and it should be replaced with a new unit.

Frequently asked questions
Do all three dispensers need to be used at the same time?
Not necessarily. The recommended dosage is 1 dispenser per 50 m³. The units in the pack can be used according to the pool’s volume or kept to replace the previous dispenser once it runs out.
How do I know when to replace a dispenser?
Once its contents have been used up, the dispenser floats on its side. At that point, it should be removed and, if treatment needs to continue, replaced with another unit.
