Calcite Neutralizer tanks with natural crushed and screened pure calcium carbonate easily neutralize acidic waters from 6.0 to 6.9. Below 6.0 a blend of calcite and ‘Corosex©” is recommended.

How does calcite work?

The calcite and calcite-blend neutralizers work by adding calcium to the water, and it will increase the calcium hardness of the water, making the water ‘harder’. However, most acidic well water is soft to begin with and after passing through the neutralizer will be harder, but not hard enough to warrant a water softener.

What causes corrosion in water pipes?

Is a downflow neutralizer good for a well?

Both upflow and downflow neutralizers are used, but generally, downflow neutralizers that have a periodic automatic backwash are much easier to maintain and tend to work better for residential well water systems.

What does a high pH water level mean?

Both low and high pH values can cause corrosion issues within a home. Water with a low pH, below 7.0, can cause a sour or metallic taste, and cause corrosion of pipes and fixtures, resulting in blue green and orange brown staining. Water with a high pH, typically above 8.5, can result in a sour or bitter taste, cause corrosion of certain metals, and result in increased scale build up, potentially leading to inefficient operation of water heaters and other water using appliances. A high pH can also cause the water to feel extremely slippery.

What does pH correction mean?

Acid Neutralizers and pH Correction. What is pH? The pH of your drinking water reflects how acidic or alkaline it is. pH stands for "potential of hydrogen", referring to the amount of hydrogen present in water, and it is measured on a logarithmic scale between 0 and 14.

What is the measure of the water's ability to buffer itself or neutralize acids?

Alkalinity is a measure of the water's quantitative ability to buffer itself or neutralize acids. Total alkalinity is a product of the total sum of carbonate (CO3), bicarbonate (HCO3), and hydroxide (OH) ions present in solution. A higher alkalinity results in a greater capacity of the water to resist changes in pH from the addition of acids.

What are the most acidic water conditions in the United States?

The most common regions for acidic water conditions in the United States are New England, the Mid-Atlantic, and the Pacific Northwest. Even within these regions, the pH and water chemistry can vary widely.
