WELL WATER TREATMENT

About Acidic pH Neutralizer Systems

That dreaded green-blue staining on your fixtures?

If you get blue or green stains on your fixtures or around drains, it is usually due to having corrosive acidic water.

Corrosive acidic water has a pH level less than 7.0. 

Corrosive acidic water causes the blue and green staining that you see around your fixtures and draining. This is from your copper pipes deteriorating into your water and appearing on fixtures and drains.

If you let this occur for too long your plumbing will start leaking and may cause major water damage and mold. Your property will need to a full re-pipe replacement.

A quality pH neutralizer filter will raise the pH level to 7.0, which is a neutral state (no longer acidic water).

Why Calcite Media Filter Treatment?

What Is Calcite Limestone Media?

Typically, when you have acidic water (low pH level), it means that the mineral content is low in your water. Minerals are what raises the pH in the water. 

Calcite is a naturally occurring calcium carbonate media that has a self-limiting property. Calcite is a crushed milled marble.

When applied properly, calcite media corrects pH just enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions.

How it functions

When acidic waters comes into contact with the calcite media, it gradually dissolves the calcium carbonate (within the calcite) to raise the pH level which neutralizes the water.

This process helps prevents scale, and the deterioration of rust, copper, lead and other metals found within the plumbing system.

SoftPro Stands By Its Products

Lifetime Limited Warranty

We really like our products,
and are confident in the quality and build.

PROGRAMMABLE CONTROL VALVE

More Power At Its Core

With the industry's best rated innovative design technology, SoftPro Elite is ready to take on even the hardest of hard water.

So when you're powering through excessive mineral content in water, SoftPro Elite puts the control in your hands.

Warranty details
Vacation Mode
Once the vacation mode feature is activated, the smart control valve will pause the water softener system from regenerating while you are away on vacation. If the water is not used for 7 days, the advanced system will do a quick refresh to help keep bacteria from growing in the softener.
 Auto System Refresh
Never run out of soft water throughout your home. If the system capacity goes below 3%, the softener will do a quick 15 minute regeneration that restores system capacity. You'll get the rest of the day with soft water. Later at 2 AM, the whole house system will perform a full regeneration.
Auto Reserve

Typically, the soft water reserve capacity will be equal to one day's worth of water usage. If you begin using the soft water reserve early in the morning — during your shower at 6 a.m. for example — you will still have enough soft water to last til the night.

In combination with the high-efficient, Auto Refresh mode feature, SoftPro Elite softeners only requires a 15% reserve capacity auto set in the programming.

Other less-efficient, cheap systems require more water, up to 30% or more capacity too.

Battery Backup
The self charging capacitor keeps date and time for at least 48 hours. The program settings will remain in the control valve's permanent memory so you can know you'll have soft water throughout your household.

Measure Your WELL PUMP FLOW RATE

Check your well pump's effective flow rate... Easy as 1, 2, 3...

Minimum Water Flow Rate Required:

The size of an iron filter or pH neutralizer system is dependent on the flow rate from your well pump. 
Please check your flow rate to select the properly sized system. Do not select a system that requires a higher flow rate.

PROPER FILTER SIZING

WATER INTELLIGENCE ENGINE

What Filter Size? 

In general, match your effective well pump flow rate to the backwash requirements to select the appropriate filter size.

Typical size is the 1.5 CUFT size, if your well pump can accommodate. An option is that you can also select a smaller size, if higher flow rates are not required.

NOTE: Minimum Well Pump Flow Rates Are Required. See Specs below or try our WISDOM tool.

Will using SoftPro pH Neutralizer Filter filter increase calcium or hardness in the water?

Yes, the SoftPro® pH Neutralizer Filter can slightly increase calcium and magnesium levels in your tap water, which may lead to a mild rise in water hardness. This is a normal outcome of the filtration process, where acidic water interacts with calcite and sometimes magnesium oxide to neutralize excess carbon dioxide.

As this chemical reaction occurs, it improves the alkalinity of the water, stabilizes pH levels, and significantly reduces the risk of corrosion within your home’s plumbing system.This adjustment in mineral content is generally beneficial and enhances overall water quality, especially for drinking water.

However, if your water supply already contains a high level of hardness, combining this system with a reverse osmosis unit or a water softener may help maintain a balanced profile. These systems complement each other and are commonly used in residential water purification setups to deliver cleaner, more stable tap water across every outlet in the home.

To maintain consistent performance, the SoftPro® system uses a backwashing function that cleans and redistributes the media. This ensures even flow and extends media life, especially in high-volume households using several hundred gallons of water per day. For properties facing broader water issues—such as hydrogen sulfide odors, microbial presence, or discoloration—this filter can be paired with ultraviolet disinfection or leak detection systems as part of a comprehensive water treatment solution.

By improving pH balance and reinforcing pipe protection, this system offers more than just clean water—it delivers long-term peace of mind. With a strong foundation in water chemistry, it provides an effective and reliable upgrade for households seeking better filtration performance, enhanced appliance protection, and noticeably better tap water at every point of use.
