Natural Chemistry Metal Free 1 Liter – Phosphate-Free Stain Prevention for Clear Pool Water

Overview

Natural Chemistry METALfree comes in a 1 liter bottle and is designed to curb staining and water discoloration caused by trace metals. The formula is phosphate-free, helping maintain balanced water chemistry while supporting a clean, inviting pool appearance. Use it as a part of a well-designed maintenance program to help protect surfaces and water clarity over time.

With a focus on metal control rather than a quick fix, METALfree offers a practical way to address common metal-related issues, like dark spots or faint color shifts, without increasing phosphate levels. This makes it a considerate addition to many pool care routines, especially when metals are suspected to influence water aesthetics.

Why METALfree matters

Metal staining and water discoloration can detract from your pool’s beauty and shine. METALfree targets the root cause—trace metals—so you can enjoy clearer water and more consistent surface appearance without heavy alterations to your existing chemistry.

Key benefits

• Protects against staining and discoloration caused by trace metals such as iron and copper.
• Phosphate-free formula, so you don’t raise phosphate levels in pool water.
• Supports crystal-clear water by reducing metal-related coloration and cloudiness.
• Compatibility with most sanitizing systems and all common pool surfaces; note: not compatible with biguanides.
• Reliable performance associated with the Natural Chemistry brand, known for a broad line of pool and spa solutions.

How it works

METALfree functions as a chelating agent, binding trace metals to prevent deposits on surfaces and in water. This targeted approach works best when integrated into a balanced care routine, rather than as a sole solution.

Real-world use ideas

• After heavy rainfall or urban runoff that can introduce metals, METALfree helps maintain a consistent water appearance.
• For pools using metal-based algaecides or outdoor equipment, it can reduce staining risk while preserving clarity.
• Homes with city water containing iron or copper may benefit from including METALfree in routine maintenance to support even, bright water looks.

Usage tips

Use METALfree as part of a broader water-care plan tailored to your pool. Follow your overall maintenance program and check compatibility with your sanitizers and surfaces. Avoid using this product with biguanides.
