The mustard algae is a tough, very fine, dusty yellow algae that settles on the walls of the pool and "flies" off the bottom of the pool when you use the broom or the vacuum cleaner that disperses it in the pool. These algae often appear after episodes of Sahara sand winds and the very dirty rains that follow. ALGI-STOP MUSTARD is the solution to get rid of it, necessarily associated as a complement to a shock treatment: - active oxygen: OXYSPEED Liquid (1L/10m3) or chlorine: RAPID CHLORINE V60 (200g/10m3) or CHLORINE SHOCK 20G (25 tablets/10m3)
