Prevents thread algae



An effective and reliable agent to treat thread algae, which can be used as a preventative as well as to fight algae, is barley straw. Barley straw inhibits algae growth through its decomposition and causes any algae present to die off.
Dennerle Algae Stop also includes humic peat, oak bark and alder fruit. These reduce and regulate the pH as algae require high pH values. A slightly golden brown colour also filters algae-promoting UV light.
