What is Corosex?

Corosex is a bead-like material used in water filtration systems as an acidic water neutralizer. The filter media corrects acidic water conditions as well as removing its corrosivity by increasing its pH value. Pound per pound, it is more effective than calcium carbonate when it comes to neutralizing water acidity.

How Does Corosex Work?

Corosex is a quick-acting media that slowly dissolves in acidic water while fixing its pH level. Although it may seem like a simple filter media, this material is special because it does an amazing job of correcting the water condition.

What are the Right Conditions for Operation?

Regular backwashing helps prevent cementing of the Corosex bed. The recommended pH level for operation is between 4.5 and 6.0. The bed depth for Corosex should be somewhere between 24 and 30 inches. For the best result, a gravel support bed is recommended.

What are the Advantages of Corosex?

There are several good reasons why you should have the magnesium oxide media, including fast-acting acidity neutralization, the capability to correct larger pH problems, and being certified to NSF/ANSI Standard 60.

What are the Disadvantages of Corosex?

Like any filtration media, Corosex has its downsides. Since it is an acidic water neutralizer, using it on your tap water will increase its hardness. Therefore, it’s necessary to have a water softener to correct the hardness after the neutralization of the acidic water. Over-correction of pH level is also a problem encountered when using Corosex in water treatment. Fortunately, there are remedies to this issue, such as using magnesium oxide media in smaller amounts.

Is Corosex an Effective Filter Media?

When used correctly and in the right conditions, Corosex will do its job effectively. When combined with calcite, you can reduce the potentially high-basic properties due to the over-correction of the filter media. Combining the filter media with other water filtration media and techniques can greatly improve the effectiveness and efficiency of the whole filter system.
