This pack of 3 MAREVA mustard algae treatments for infected pools - 3 kg will help you eradicate mustard algae from your pool. A veritable nightmare for pool owners, these mustard-yellow algae, composed of infected dust from the Sahara winds, are particularly hard to detect, moving with the slightest movement, and to treat. This purifier will get rid of these tough algae. First, check your pool's pH, which should be between 7.2 and 7.4. Next, you'll need to carry out an intensive pre-cleaning to remove any algae germs clinging to the walls - a crucial step if the treatment is to be effective. This fungicidal anti-algae product must then be combined with an oxidizing shock treatment and a clarifier to ensure hygienic water. We strongly recommend combining Revatop 12% + Top 3. (sold separately on our website, or opt for our all-in-1 pack for a more economical and practical option). We recommend carrying out the treatment a second time for optimal cleaning, and a 3rd time as a preventive measure. For regions that are more exposed to the wind and are more subject to this type of pollution, it is advisable to carry out regular preventive treatments after treatment, at the rate of 2 times per season. Please also note that it's important to thoroughly clean all equipment that has come into contact with pool water (toys, inflatables, etc.) to remove all germs.
