What Is Corosex pH Adder and How Does It Work?
Corosex is a powerful pH correction media used in water treatment systems to neutralize acidic water.
It is made from high-purity magnesium oxide (MgO), a naturally alkaline mineral that reacts with acidic water to raise its pH level.
Why pH Balance Matters
Water that is too acidic can cause:
• Corrosion in pipes
• Metal contamination in drinking water
• Damage to appliances
• Reduced lifespan of plumbing systems
Maintaining a neutral pH helps keep water systems safe and stable.
The Corosex Neutralization Process
When acidic water flows through a filtration tank containing Corosex media:
-
Water contacts the magnesium oxide media
-
The media slowly dissolves
-
Acidity is neutralized
-
Water pH rises toward neutral
This process stabilizes water chemistry and prevents corrosion.
Faster Reaction Than Calcite
Corosex reacts faster than calcite because magnesium oxide has a stronger neutralizing capacity.
This makes Corosex ideal for:
• Strongly acidic well water
• Systems requiring faster pH adjustment
• Blended neutralizer media systems
However, because Corosex reacts quickly, it is often blended with calcite to prevent overcorrection of pH.
