RE: Bottom Cleaning

The hard scale commonly found on the surface of zinc anodes is Zinc Carbonate (ZnCO3). Carbonate (CO3) occurs in all bodies of water and originates from atmospheric carbon dioxide gas (CO2) naturally dissolving into the water. In general you do not need to be concerned about this scale as it only affects the maximum output amperage of the anode, not the anodes required trickle output necessary to maintain effective corrosion protection. Zinc Carbonate is water insoluble, but can be readily removed by either alkalies or acids.
