#17 Magnesium Anode Bag for Below Ground Propane Tanks for Sale

A below ground propane tank is a long-term investment, designed to provide decades of safe, reliable fuel storage. But to protect that investment, you need to defend the tank against one of its greatest threats—corrosion. That’s where the #17 Magnesium Anode Bag comes in.

At PropaneTanksandContainers.com, we offer the #17 magnesium anode bag for sale, trusted by homeowners, businesses, and installers nationwide. When you buy from us, you’re choosing a product engineered to extend the lifespan of your propane tank while giving you peace of mind.

Why Use a Magnesium Anode Bag for Propane Tanks?

Steel propane tanks are strong, but when installed underground, they face constant exposure to soil, moisture, and natural minerals. Over time, this exposure can lead to electrolytic corrosion, slowly breaking down the tank wall. Left unchecked, corrosion can shorten your tank’s life and compromise safety.

The #17 magnesium anode bag is the solution. Acting as a sacrificial anode, it corrodes in place of your propane tank. Instead of the steel tank walls breaking down, the magnesium absorbs the corrosion, preserving the integrity of your propane tank for decades.

In other words: the anode bag sacrifices itself to protect your tank. That’s why every below ground propane tank installation should include at least one magnesium anode bag.

Specifications of the #17 Magnesium Anode Bag

Every #17 magnesium anode bag we sell is manufactured to meet strict industry standards for underground propane tank protection.

Size & Specifications:

• Model: #17 Magnesium Anode Bag

• Core Material: High-purity magnesium (99.5% minimum purity)

• Weight: 17 lbs (approximate active magnesium weight)

• Dimensions: Around 3.5” diameter x 32” length

• Backfill: Cotton bag with special low-resistivity mixture (gypsum, bentonite, sodium sulfate) to enhance performance

• Lead Wire: Pre-attached steel core wire with 10–12 feet of insulated copper wire for easy connection to the tank

• Application: Below ground steel propane tanks, underground storage vessels, and similar applications

This combination of magnesium, cotton bag backfill, and steel core wire ensures maximum performance in protecting your tank against corrosion.

How Does the #17 Magnesium Anode Bag Work?

When installed near a below ground propane tank, the #17 anode establishes a protective electrical circuit. Magnesium has a much higher tendency to corrode compared to steel. By design, the anode attracts corrosion away from the tank walls, slowly deteriorating over time.

The cotton backfill and special chemical mixture keep the anode moist and active, ensuring consistent protection for many years. As the anode corrodes, it provides ongoing cathodic protection, effectively extending the life of your propane tank far beyond what it would achieve without protection.

How Long Does a #17 Magnesium Anode Bag Last?

On average, a #17 magnesium anode bag will last between 15–20 years, depending on soil conditions, moisture, and tank size. In harsher soils or areas with higher electrical conductivity, the anode may corrode faster. That’s why it’s always recommended to have your propane supplier test the cathodic protection levels periodically.

By replacing anodes as needed, you can ensure your below ground propane tank continues to perform safely for 30–40 years or longer.

Installation of the #17 Magnesium Anode Bag

Professional installation is essential for ensuring the magnesium anode bag works effectively. During installation:

• The anode bag is buried near the tank, usually at each end of the vessel.

• The pre-attached wire is connected directly to the tank’s steel surface.

• The bag is surrounded by soil, which interacts with the backfill to activate the protective system.

When properly installed, the #17 magnesium anode bag immediately begins working to divert corrosion away from your propane tank.

Who Needs a #17 Magnesium Anode Bag?

If you are installing or maintaining a below ground propane tank, you need an anode bag. The #17 size is a common standard used for tanks ranging from 250 gallons to 1000 gallons and larger, depending on soil conditions and the number of anodes installed.

Whether you’re a homeowner relying on propane for heating, a farm owner with large fuel needs, or a business managing propane storage, the #17 magnesium anode bag is essential for tank protection.

Frequently Asked Questions

How many #17 magnesium anode bags do I need for my propane tank?
Most 500–1000 gallon tanks require two anode bags, but the exact number depends on soil conditions.

Can I install the anode bag myself?
Installation should be handled by a licensed propane professional to ensure proper grounding and effectiveness.

What happens when the anode bag corrodes completely?
It needs to be replaced to maintain protection. Your propane provider can test the system periodically.

Is magnesium better than zinc for anode bags?
Yes. Magnesium has a more negative potential, making it more effective in soil environments where propane tanks are buried.
