Prepare Your Pool for Metal Stain Removal

Preparing Your Pool for Metal Stain Treatment

Objective 

This guide outlines the mandatory chemical preparation steps required before applying any metal stain remover, ensuring the treatment is successful on the first try.

Why Preparation is Everything 

Applying a stain remover without prepping your water is like trying to paint a dusty wall—it simply won't work. The active ingredients in high-quality stain removers (like Iron Stain Treat™ or Copper Stain Treat™) are reducing agents. Chlorine and bromine are oxidizers. If your chlorine or pH levels are too high, the oxidizers in the water will instantly attack and destroy the stain remover before it ever has a chance to lift the stain from your pool wall. Taking 24 hours to properly lower these chemical barriers guarantees a successful, money-saving treatment.

Prerequisites

  • A reliable liquid test kit to measure Chlorine, pH, and Total Alkalinity.

  • A supply of No Mor Chlor™ (chlorine neutralizer) and No Mor Muriatic Acid™ (pH/Alkalinity decreaser).

Step-by-Step Instructions: The Preparation Phase

1. Disable All Sanitizer Equipment

  • Navigate to your pool equipment pad and turn the System Power to the OFF position.

  • Unplug your Salt Water Chlorine Generator, turn off your automatic chlorinator, or physically remove any floating chlorine dispensers from the water.

2. Lower the Chlorine to Near Zero

  • Your chlorine level must drop below 1.0 ppm (ideally closer to 0 ppm).

  • You can allow the sun to naturally burn off the chlorine over a few days, or for immediate results, add a chlorine neutralizer like No Mor Chlor™ directly to the water according to the label instructions.

  • Pro-Tip: To prevent algae from blooming while the chlorine is at zero, add a maintenance dose of a polyquat algaecide like Poly60 Treat™.

3. Lower the pH and Alkalinity

  • Stain removers work best in a slightly acidic environment. Using a dry acid like No Mor Muriatic Acid™, lower your pool's pH to 7.2.

  • Simultaneously, ensure your Total Alkalinity is lowered to 80 ppm or below. Pre-dissolve the dry acid in a clean bucket of water and pour it around the perimeter of the pool with the pump running.

4. Apply Your Stain Treatment

  • Once the chlorine is below 1 ppm and the pH is at 7.2, your water is perfectly primed. You may now apply your specific United Chemical stain treatment directly to the affected areas.

Troubleshooting Note: Cloudy Water After Treatment

  • It is completely normal for the pool water to turn slightly cloudy after a successful stain treatment. The metals have been lifted from the walls and are now suspended in the water. Follow up with a sequestering agent and run your filter continuously for 48 hours to clear the water.
