How to reopen the pool ?

Reopening your pool after winter is a crucial step. 
Before being able to swim, several steps need to be followed in order to kick off the season in the best conditions. 
You will then be able to enjoy clear, disinfected and balanced water throughout the summer. You can also watch the full tutorial in video here.
