PURPOSE: To provide a green algae eliminating composition which is mass-produced at low cost, prevents secondary environmental pollution and maximizes green algae eradication efficiency. CONSTITUTION: A green algae eliminating composition comprises 30 to 35 wt.% of magnesium oxide(MgO), 25 to 30 wt.% of titanium dioxide(TiO2), 10 to 15 wt.% of magnesium chloride(MgCl2), 3 to 7 wt.% of sodium hydrogen carbonate(NaHCO3) and 15 to 20 wt.% of silicon dioxide(SiO2) as principal components, wherein the green algae eliminating composition is prepared by adding activated carbon, charcoal powder and germanium powder as additives in addition to the principal components, and wherein the green algae eliminating composition is prepared by adding pine needle extract that is a crude drug component as an additive in addition to the principal components.
