Description

FreshWater Stain & Scale Defense

Overview

FreshWater Stain & Scale Defense is a 16 fl oz weekly maintenance liquid that prevents two of the most damaging — and most preventable — problems in hot tub ownership: white calcium scale on heaters, jets, and spa shells, and rust, green, or brown staining from dissolved metals like iron, copper, and manganese. The active organic polymers chemically bind to minerals and metals in your water, holding them in suspension so they can't deposit onto surfaces or coat your equipment.

Especially important if your fill water comes from a well: Well water commonly contains iron (which causes rust-colored stains), copper (which causes green stains), and manganese (which causes brown or black stains). Even municipal water often contains low levels of these metals. Without a sequestrant like Stain & Scale Defense added at start-up, those metals will deposit onto your spa shell, jets, and heater within weeks.

What’s in the Box

  • 1 x FreshWater Stain & Scale Defense — 16 fl oz bottle

Key Features

  • 16 fl oz bottle — typically 4 months of weekly maintenance for a 350-gallon residential spa
  • Organic polymer sequestrants — chemically bind to calcium, iron, copper, and manganese
  • Prevents both scale AND staining — one product handles two distinct problems
  • Spa-safe to use — bathers can soak while the product is working
  • Works with all sanitizer systems — chlorine, bromine, ozone, biguanide, FreshWater Salt System, and ACE Salt System
  • Especially valuable for well water — handles the iron and manganese that municipal water rarely has

Directions

  1. Fill the spa with fresh water and balance pH (7.2–7.8) and alkalinity (80–120 ppm).
  2. Add 2 oz of Stain & Scale Defense per 500 gallons of spa water to the filter compartment with jets running.
  3. Circulate for at least 2 hours — owners with well water or visible iron/copper at fill should circulate for the full 24 hours before adding chlorine, MPS, or any other oxidizer (see warning below).
  4. Add your sanitizer (chlorine, bromine, etc.) only after the sequestrant has had time to bind any metals.

Weekly Maintenance

  1. Test water chemistry with FreshWater 5-Way Test Strips. Confirm pH and alkalinity are in range.
  2. Add 2 oz of Stain & Scale Defense per 500 gallons to the filter compartment with jets running.
  3. Circulate for at least 1 hour. You may use the spa while the product is working.
  4. Repeat weekly throughout the life of the water (typically 3–4 months for traditional spas, up to 12 months for FreshWater Salt System spas).

    Pro tip: well water owners read this: If your fill water has visible iron staining, a metallic taste, or a rust-colored tint, add Stain & Scale Defense FIRST and wait 24 hours before adding any oxidizer (chlorine, MPS, ozone, or running a salt cell). Oxidizers will drop dissolved metals out of solution as visible stains before the sequestrant has time to bind them. The 24-hour delay protects your spa shell from permanent staining.

    Compatibility

    • Compatible with chlorine, bromine, ozone and biguanide sanitizers.
