Magnesium rods are excellent sacrificial rods, used to protect the inside metal surface of your water heater tank. The magnesium corrodes instead of your tank. Magnesium anode rods tend to be consumed quicker than Aluminum or Aluminum/Zinc/Tin anode rods due to the higher voltage they create during the sacrificial process. Even though Magnesium anode rods normally corrode at a slightly faster rate than most anode rods, dissolved magnesium in water can offer many health benefits.
