AQUAFORTE COPPER ELECTROLYZER An ideal en effective method against (blanket)weed. The Copper Electrolyser is installed before the (swim)pond return inlet. The pond water flows through the Copper Electrolyser unit. A copper unit, or Electrolyser, is positioned within the housing, and the copper unit discharges a minimal amount of copper into the water flowing through the housing. These copper ions (Cu2+) in the water have a positive charge and destroy the cell walls of algae, bacteria, viruses and other primitive organisms. As the cell wall is thereby damaged, these organisms are no longer able to take up any nutrients, and are therefore unable to multiply. The process of applying a positive charge to copper is called copper electrolysis. Inlet/outlet: Ø50mm. PLEASE NOTE: (too much) copper is harmful for fish! After 2 weeks the unit will automatically switch off. Test the copper level in the water and activate the unit again if necessary. This will prevent the build-up of too much copper in the water. Not to use in water that contains iron (like ground water).
