It is important to keep in mind that water pH levels indicate how healthy the water is. Having a decent water pH level with you is very important to consider. Aluminum anode rods contain more natural metals, and that is why they react more. When it comes to soft acid water, this is why it starts to corrode the anode rod much faster than any other type. In such a situation, having an aluminum rod is never the ideal option to choose.
On the other hand, magnesium rod contains a lower amount of metals. For soft water situations, the amount of pH levels is much lower. This is why choosing a magnesium anode rod could benefit you in many ways. Anode rod replacement is always important when it comes to the use of anode rods. They require time to time replacement for continuous performance. Irrespective of your water quality, the anode rod might turn to wear out. Aluminum anode rod tends to corrode as time goes by. The anode rod may break into pieces if it is not replaced after a certain time because of mild or strongly acidic water.
Consequently, replacing such a corroded rod will always be difficult and a tough challenge in hand. Magnesium anode rods do not tend to corrode. Only an outer layer of this rod may fade away to reduce levels of contamination. Thus, replacing a magnesium rod will never be a difficult challenge for you.
You can easily take out the entire rod following a DIY procedure. Aluminum anodes tend to be cheaper than magnesium anode rods. A magnesium rod will generally last less than an aluminum rod. One issue with aluminium rods is that the corrosive material that is formed on the anode tends to harden and sink to the bottom of the water tank. This can potentially find its way into your taps and cause issues down the line. Our overall decision in the water heater anode rod aluminum vs magnesium argument is that magnesium anode rods are the better choice when deciding which anode to buy for your water heater.

If the internal components of the heater get damaged completely, there will be no option left but to buy a new heater. Thus, you must check the situation of the anode rod after the warranty period is over. Usually, they last for about years.
You must keep one thing in mind that neither of the heaters will serve you with a warranty and a maintenance service if the heater is filled with hard water and the locality is being highly affected because of this.
The aluminum rods are the slowest performing anode rods built from aluminum. To be fair, this type of rod is much less expensive when you compare it with the magnesium or any other type of rods. Since the working mechanism is slow, this is the reason why it produces low voltage during electrolysis. It is intended to slow down the corrosion. Most of the heaters come with anode rod as a standard option because of this mechanism.
The best part of using the aluminum anode rod is for places where there are a lot of sulfates present in the water. The anode rod works specifically to change the sulfates into hydrogen sulfides that can reduce the levels of contamination.
The main feature of the magnesium anode rod is to prevent the internal components from corroding. The working mechanism for this is simple and it is quite effective. It is done because the rod diverts the entire corrosion to them. Because of such a high-performance mechanism, these rods are mainly used in areas that receive soft water.
As a result, they have a much shorter life span as compared to the other anode rods available. To work with this, the magnesium rod also comes with a higher voltage and may be more reactive than others. Aluminum anode rods are cheaper than magnesium anode rods. They are a good option if you live in an area that receives hard water. For this reason, magnesium anode rods offer a better option. I needed a new anode rod for my Atwood water heater and started doing research.
I came across this information that I thought was very helpfull. I ordered a magnesium rod, need I say more! Thanks for the info!! Research indicates this is the formation of hydrogen sulfide due to sulfates in the water reacting with the magnesium rod. The smell is pretty bad. September 11, January 3, versus Home.
