Ensure your water's pH levels are perfectly balanced with the Aqua Science pH Neutralizer System. Designed specifically for homeowners dealing with acidic water issues, this advanced system provides an effective solution to neutralize acidic water in your household. Neutralizing acidic water is crucial for protecting your plumbing from corrosion, preventing leaks, and improving overall water quality for safer use throughout your home. With its digital control valve, the system allows for precise management and easy operation, making it an ideal choice for those seeking reliable water treatment.
Digital Control Valve for precise control and easy management
No control box required
Treats low pH, acidic water with a water filter that uses calcite, a common filter material used to neutralize acidic water
The tank uses media as a passive treatment with no chemical injections, which makes ongoing correction simple
Corosex can be blended with calcite to raise the pH for more aggressive correction when needed
Includes 1 cu. ft of calcite, sleeves of Corosex and gravel, a funnel and cap, and necessary fittings
Available in tank sizes: 9" x 48", 10" x 54", 12" x 52", and 13" x 54"
Helps reduce problems caused by corrosive water in plumbing, including damage to copper pipes and galvanized steel lines, with whole-home protection that can also benefit rural or agricultural properties using acidic water
The self-limiting property offers clear advantages: the media corrects pH until levels reach a neutral range and can improve sour or metallic-tasting water throughout the house
Lifetime Warranty for peace of mind
This system includes everything you need for effective acidic water treatment:
Aqua Science Digital Control Valve
1" by-pass
1 cu. ft of calcite — calcium carbonate media that neutralizes low pH water and needs periodic replenishment to stay properly applied
1 sleeve of Corosex — used with calcite to add extra correction when additional pH adjustment is needed in pH neutralizer (acid neutralizing) water filtration systems
1 sleeve of gravel
Funnel and cap
1" FPT barb and 90 elbow
Acidic water is defined as water with a pH below 7.0; water below 6.5 is considered acidic and corrosive. Understanding the severity of acidity is important before selecting a treatment system. Using a free well water test kit can help you determine the exact pH level. Water at pH 4.5 is extremely acidic, while a pH neutralizer is generally recommended when pH is below 6.8.
When water comes into contact with the media, minerals dissolve to add alkalinity and bicarbonate, which helps raise water toward neutral at pH 7 and supports calcium hardness stability despite changes in water chemistry.
This system helps reduce blue-green staining on sinks and other fixtures, because the change toward less acidic water lowers corrosive conditions and the risk that acidic water may leach lead, copper, iron, manganese, zinc, and arsenic from pipes and the rest of your home's plumbing. This can help prevent leaks and pinhole leaks, reducing long-term exposure concerns for people in the home.
To keep your system running efficiently, follow these maintenance steps:
Perform periodic backwashing to support flow rate.
Check and add media as needed—typically around the listed 12-month replacement time or within the usual 6- to 36-month maintenance window, and many owners check media levels at least once a year.
If you have questions or need to find replacement parts, contact Aqua Science, the most trusted name in water treatment after a water test to confirm what is needed.
