Certainly! While freshwater is not really as corrosive as saltwater it might cause corrosion after a while. The sort of anode essential differs too. For freshwater use, magnesium anodes or aluminum anodes are recommended, as zinc will not be as efficient in freshwater.
An easy means of safety connects protected metallic to a more effortlessly corroded “ sacrificial metallic “ to act as being the anode. The sacrificial metal then corrodes in lieu of the secured metal.
An additional typical kind of corrosion is electrolysis. Electrolysis is described given that the “chemical decomposition produced by passing An electrical latest by way of a liquid of Answer made up of ions.

A simple approach to safety connects secured steel to a more simply corroded “ sacrificial steel “ to act as being the anode. The sacrificial steel then corrodes in place of the shielded metal.
