Claims26
A method for reducing, preventing or removing algae from fish tank water containing fish, comprising filtering the fish tank water with a metallic mesh or cloth selected from the group consisting of bronze alloy, brass alloy, or copper and blends thereof, the fish tank water having a sufficiently low chlorine content without posing injury to the fish, and without the mesh or cloth undergoing chemical degradation by the chlorine, the method also being effective in hard water.
A method for reducing, preventing or removing algae from water contained in hot tub spas, slews, water ponds and cooling towers, comprising filtering the water therein with a metallic mesh or cloth selected from the group consisting of bronze alloy, brass alloy, or copper and blends thereof, the water having a sufficiently low chlorine content to avoid chemical degradation of the mesh or cloth by the chlorine, the method also being effective in hard water.
A filter for an aquarium, consisting essentially of a metallic mesh or cloth selected from the group consisting of algicidal amounts of bronze alloy, brass alloy, copper, and mixtures thereof.
