String algae that form a symbiotic relationship with slime fungus can rarely be permanently removed using mechanical methods. Algolon uses active oxygen to offer a solution: It immediately triggers oxidation processes that decompose the cell structure of the thread algae. The mucus is also stopped by this patented combination for multiple effects. Algolon does not contain heavy metals or organic biocides and does not create new organisms; it dissolves completely in the water. The dead algae can be fished out of the water after just a few hours.
