Types of water heater anodes
Magnesium anodes
Standard water heaters are equipped with the magnesium anode rods (identifiable by weld bead on the plug), and they work the best where water is not hard (softer). If the water is hard, magnesium anode rod in hot water heater do not last very long, usually couple of years. Magnesium anodes are used as they corrode at a faster rate than the iron.
Aluminum anodes
For extremely hard water and where conductivity is high, an aluminum zinc anode rod might be a solution.
If you live in the area where the water supply has a high PH (8+), water condition will react with the aluminum anode rod and form the excessive amounts of aluminum hydroxide. Gel like substance will then reside on the rod and bottom of the tank making the above described noise.
Zinc anodes
If you experience rotten egg odor coming out from the hot water tap, which is the most common complaint associated with the anode; one solution to reduce the smell is to install a zinc anode rod. This might be a good solution when replacing already depleted one as it never comes as factory installed.
Zinc anodes are actually aluminum rods with a small portion of zinc. The proportion is 1:10, and zinc is added to fight the sulfur (rotten egg) smell from the water.
If using chlorination procedure to eliminate various bacteria that are causing the odor, remove the rod and bring it back when done.
Note: Removal of sacrificial anode, for any reason will void the warranty and affect the tank longevity.
Flexible anodes
You might also want to consider installing a flexible anode rod in hot water heater since it provides more flexibility. The rod is divided into several smaller sections (links), which makes the whole rod instead of one solid piece, bendable, which would be great if the unit is installed in tight spaces, or there is limited overhead clearance.
