Natural Chemistry 17511NCM – SCALEfree® Pool & Spa Water Treatment (2 L Bottle)

The Natural Chemistry 17511NCM, sold under the name SCALEfree®, is a liquid treatment designed to prevent mineral scale buildup and metal staining in pool and spa water. It helps protect pool surfaces, salt systems, heaters, and plumbing by keeping calcium, iron, copper, and other minerals in solution instead of allowing them to precipitate out and form scale or stains.

Key Features

• Phosphate- and acid-free formula — avoids the problems associated with traditional acid-based stain/scale treatments.
• Protects against scale formation from hardness (calcium, magnesium) and metals (iron, copper, etc.).
• Helps prevent staining and scaling on pool surfaces, heaters, salt-generator cells, plumbing lines, and other equipment.
• Compatible with all common pool sanitizing systems (chlorine, bromine, salt, mineral, etc.), and safe for use with standard pool surfaces and finishes.
• Easy-to-apply liquid — no need for dilution; simply pour directly into pool/spa with circulation running.

Specifications

Typical Use & Dosage Guidelines

• Use SCALEfree® upon filling a new pool, after refilling, or anytime hardness or metal levels are elevated.

• Avoid using with biguanide sanitizer systems; safe for chlorine, bromine, and saltwater systems.

Why It’s Useful

SCALEfree® is a proactive maintenance chemical that helps extend the life of pool heaters, salt cells, and other metal/plastic equipment by reducing scale buildup and preventing unsightly stains on pool surfaces. It’s especially beneficial in areas with hard water or high mineral content, as well as for pools with salt systems or frequent water replenishment — making it a valuable product for pool owners and pool-supply retailers alike.
