pH Neutralizer (Acid Neutralizing) System & Fleck 5600 12 Day Timer

What is a pH Neutralizer System and Why is it Needed?

A pH neutralizer system is a water treatment device that raises acidic water pH levels. Acidic well water, typically with a pH below 6.8, can cause corrosion in plumbing, leach metals like lead and copper into the water, and damage appliances and infrastructure. The pH scale ranges from 0 (acidic) to 14 (alkaline). pH neutralizers are used in residential well water treatment to protect plumbing and improve water quality. They help protect infrastructure from corrosion and support downstream water treatment processes.

This pH neutralizer system treats acidic well water by using calcite and corosex media to raise low-pH water to a stable, non-corrosive range. Calcite, a natural calcium carbonate water filtration media, neutralizes water with pH below 6.5 and dissolves slowly to raise pH levels while helping reduce corrosion-related water-quality and plumbing problems. Common neutralizing media include calcite and magnesium oxide, with this range focused on calcite and corosex for common well-water pH correction needs, making it easier to find the right media setup for typical applications.

The neutralization process involves alkaline media dissolving in acidic water. As acidic water comes into contact with alkaline media inside the tank, the neutralization process helps protect plumbing, appliances, and whole-house water systems from corrosion and from lead, copper, and other metals leaching into the water, reducing the water-quality and plumbing problems acidic water can cause.

How the System Works

As acidic water flows through the tank, it comes into contact with alkaline media such as calcite and corosex. The neutralization process involves alkaline media dissolving in acidic water, which raises the pH to a neutral or slightly alkaline range. This helps protect plumbing, appliances, and water systems from corrosion and metal leaching, ensuring better water quality throughout the home or facility.

Who Should Use This System

For homeowners with acidic well water, agricultural properties, light commercial sites, and contractors installing or maintaining these systems—especially when sizing, setup, or installation questions come up, and where some residential setups can be installed in less than an hour—Aqua Science’s water system products support this range. This system centers on calcite-media treatment rather than automatic systems that adjust pH using sensors and chemical dosing, and covers the components, operation, sizing, and maintenance that determine performance. Sizing and setup information is available in the store resources, where shoppers can also read customer review content, comments, and setup feedback. That performance is driven by the Fleck 5600 12-day timer control valve, tank sizes, neutralizing media, and proper service flow so water can reach and stay in a stable range that supports biological performance, typically 6.5 to 8.3, and so treatment steps such as coagulation and flocculation can work properly. Product videos may also help explain valve operation or sizing before purchase.

The System Includes a Whole House pH Neutralizer for Acidic Well Water

• 1 cu. ft. of Calcite to add during installation or refill; more media may be required for a larger system size or more aggressive application

• 1 sleeve of Corosex

• 1 sleeve of gravel

• 1" stainless steel by-pass

• Funnel with cap for the tank cylinder opening, designed to accept the included media and help keep it in place during filling
