Magnesium anodes are the go-to choice for marine boilers because they attract corrosion much faster than the steel tank does. Seeing a rod pulled out that is half its original size shows that it is doing its job well. Without this sacrificial layer, the salt air and water quickly eat away at the tank lining. These anodes fit securely into the mounting points to guard the boiler internals against constant moisture exposure. Keep an eye on the state of the metal during your seasonal checks to ensure the tank stays clean and leak-free.
