🛡️ Natural Chemistry Spa Metalfree™ – 1 Liter (33.9 fl oz)

Protect your spa from stubborn metal stains and keep your water crystal clear with Spa Metalfree™, a powerful metal chelating agent designed for hot tubs and spas.

• ✨ Prevents Metal Staining: Effectively binds and removes dissolved metals such as iron, copper, and manganese to stop stains and discoloration before they start.
• 💧 No Phosphate Increase: Unlike many stain and scale treatments, Spa Metalfree™ will not raise phosphate levels in your water, supporting easier water management.
• 🔄 Compatible with Most Sanitizers: Safe for use with chlorine, bromine, ozone, and saltwater sanitation systems. Do not use with biguanides.
• 🧽 Safe for All Spa Surfaces: Use confidently on acrylic, fiberglass, and vinyl-lined spas.
• 🧴 Easy Maintenance: Ideal for weekly spa care or after each refill to prevent scale and staining.
• 🛠️ Part Number: 74120NCM (formerly labeled as Spa Metalfree 1L, SKU: 74120NCM)

Directions for Use:

• For initial treatment or after draining/refilling, add 1 capful (4 oz) per 400 gallons of water. Pour slowly and evenly around the edge with the pump running.
• For weekly maintenance, add 1 oz per 400 gallons (about 1/4 capful), distributing evenly.
• Important: Avoid dosing at the same time as clarifiers, flocculants, or polyquat algaecides. Wait at least 24 hours between additions to prevent cloudy water and reduced effectiveness.
• Do not exceed recommended doses.
• Not for use with biguanide sanitizers.
