What does the "Clear Water Without Algae Guarantee" mean?

If after 60 days (at water temperatures above 10°C) your pond water is still not clear or algae are still present, you will receive the 3rd application free of charge from us without any ifs or buts, in accordance with our Terms and Conditions. We only require your pond size as well as a photo of your pond before the 1st application and a photo 30 days after the 2nd application from Natura Summarum.
