Product description GartenteichDirekt thread algae stop liquid is a thread algae killer and helps safely and reliably with thread algae in the garden pond. Thanks to its liquid formula, it is very easy to use and can be used at temperatures from 5 degrees Celsius to high summer temperatures. When thread algae grow in the garden pond, they multiply rapidly and quickly become annoying. Growth should be stopped as soon as possible. Thread algae stop liquid helps reliably and safely as an algae killer. It removes important nutrients from the algae, so that they die after a short time and can no longer multiply. Resettlement is safely prevented and if you give the pond a little time, it becomes beautiful algae free again. Application: Keep out of the reach of children. Shake well before use. For three weeks, add 50 ml filamentous algae stop liquid to 1500 litres of garden pond water once a week. It is best to put the product in a watering can with pond water first and then spread it on the pond surface. Repeat the application once a week for 3 weeks. After that, a significant algae decline should be noticeable. Preventively, thread algae stop liquid can be used with half the dosage once a week or every 14 days (depending on needs).
