AlGo Direct
Use biocides carefully. Always read the label and product information before use!
AlGo Direct specifically treats local areas affected by thread algae, for example, in watercourses. The algae are killed within a few hours. The active substance breaks down into its naturally occurring components. This makes AlGo Direct suitable for use in swimming ponds. A safe application requires a carbonate hardness of at least 3 °dKH.
