Zinc Anode To Reduce Corrosion In Salt Water Pools

Reduce Corrosion with a Zinc Anode

If you’ve noticed saltwater pool corrosion problems lately, the solution for these issues is a sacrificial zinc anode. A zinc anode keeps the metal parts and other hardware in your pool from becoming corroded. The device works by conducting currents of electricity that pass through the water after the production of chlorine. A zinc anode is pretty easy to set up and is an affordable way to make sure your saltwater pool remains safe. The anode is also available in a number of sizes and shapes so that you can easily install it in your pool.

Zinc Anodes and Swimming Pool Corrosion

Understanding pool chemistry can be challenging. However, the main principle of anodes is easy. Electricity normally flows through the water in your pool and the metal components in the pool. With the installation of a zinc anode, the anode attracts electricity. Over time, the anode will become the sacrificial element, so that all the metal components of your pool won’t become corroded.

While sacrificial zinc anode devices have been used for years by those in the marine industry, they are fairly new when it comes to swimming pool care. The main function of the anode is to corrode before the other metal parts that are part of the swimming pool system. Zinc anodes are also beneficial because they work on pools of any size.

Once you have a zinc anode installed in the pool, your steps, ladder, and parts of the pool heater are likely to be protected by the device. The anode will protect virtually anything in the pool that is made of metal and placed under the water.

How Does a Sacrificial Zinc Anode Work?

The metal items in your pool are producing electrical voltage. If you have a saltwater pool, there’s also a salt cell included in your pool care system. The cell converts the salt into sodium and active chlorine. These substances reduce and repel bacteria in the pool passing causing electrons to pass through the pool. This makes the metal parts in the pool at risk of corrosion. Your pool filter, steps, ladders, light fixtures, filter, and heater could become corroded and discolored if the chemical balance of the pool is altered.

A zinc anode device uses cathodic protection to protect the metal components of your pool. Zinc is more active in terms of voltage than other metals. This causes zinc to break down before damage is done to the surrounding metal. The protective nature of zinc makes it an ideal addition to your pool. Mineral reduction and oxidation occur on the zinc anode instead of on the metal pool components. This helps to keep your pool area looking like new for a considerable period of time.

Maintaining a Zinc Anode

It’s important to watch your zinc anode to ensure it continues working properly. Take a good look at the metal of the anode every few weeks to see if it has broken down. Most zinc anodes will last anywhere from 6-12 months. Before you close the pool for the fall and winter, make sure that the anode works well. If you notice any degradation before closing the pool, it will be worse once the weather warms and you’re ready to swim again.
