Water maintenance

A swimming pool not only provides cooling & fun but also requires maintenance. 🏊
A well cared for pool with clear water goes hand in hand with the right maintenance products.

Measuring is knowing so use test strips to keep a close eye on the pool values (pH, chlorine & alkaline value). 
That way you can safely enjoy a fresh splash! 

Don't know where to start? Poolboy Marcel is already waiting with his best maintenance tips: 
a summer-ready pool in 5 steps!
