Tired of Turquoise Stains?
The problem
Blue-green stains on sinks, tubs, and fixtures are a telltale sign that copper is leaching from your plumbing. This corrosion doesn’t just discolor your surfaces; it signals that your copper pipes are deteriorating, which can lead to costly pinhole leaks and water damage over time.
The root cause of these turquoise stains is acidic, aggressive water with a low pH that eats away at copper piping. When water's pH is too low, it creates a corrosive environment that dissolves copper ions into your water supply. This not only causes unpleasant metallic tastes but also weakens your plumbing infrastructure.
Ignoring this problem means continuing copper loss, increasing the risk of pinhole leaks that can cause water damage behind walls or under floors. It also exposes your household to water that tastes metallic and potentially contains elevated copper levels, which is undesirable for cooking and drinking. Addressing the acidic water is essential to protect both your home and your health.
How it works — the calcite / mgo neutralizer that fixes it
The core of the Copper & Blue-Green Stain Solution is a calcite and magnesium-oxide (MgO) neutralizer bed housed in a durable fiberglass mineral tank. This media gently raises the pH of your water, neutralizing its acidity to stop the corrosive action on copper pipes throughout your entire home.
As water flows through the calcite/MgO bed, it is buffered to a safer pH level that prevents further copper leaching. This whole-house treatment protects every faucet and appliance, eliminating the source of blue-green stains and the risk of pinhole leaks. For drinking and cooking water, an optional under-sink reverse-osmosis system can be added to reduce copper already dissolved in your water.
Maintenance is simple: the system includes a backwashing control valve that periodically cleans the media to maintain effectiveness. Your complete system comes pre-assembled and factory-programmed to your water test, ensuring the correct size and components. Installation is straightforward with included instructions and fittings, with no hidden parts requiring a plumber.

Frequently asked questions
What causes blue-green stains on my fixtures?
Blue-green stains are caused by copper leaching into your water from acidic, corrosive water. This low pH water dissolves copper from your pipes, which then deposits as staining on surfaces.
How does the neutralizer stop copper corrosion?
The calcite and magnesium-oxide media raise the pH of your water to neutralize its acidity. This higher pH water no longer corrodes copper pipes, preventing further leaching and stains.
Will this system remove copper already in my water?
The whole-house neutralizer stops new copper from leaching, while the optional under-sink reverse osmosis stage can reduce copper already dissolved in your drinking and cooking water.
How often does the system need maintenance?
The system includes a backwashing valve that automatically cleans the media bed as needed, minimizing maintenance efforts.
Can I install this system myself?
Yes, the system ships pre-assembled with clear instructions and all necessary fittings, and contains no plumber-only parts.
How do I know which size system I need?
Sizing is done free based on your water test and number of bathrooms. You can also talk to a water expert for a free, no-pressure consultation.
