## Overview

Pool Mate Metal Out Stain and Mineral Inhibitor is a powerful sequestrant designed to prevent and remove metal-induced discoloration and stains in swimming pools. Ideal for use during pool openings, closings, and regular maintenance, it protects plumbing and pool surfaces from rust, scale, and mineral buildup. Each quart treats up to 10,000 gallons, ensuring easy, effective dosing for consistently clear, inviting water.

## Description

This product helps prevent discoloration of pool water due to iron, calcium, manganese, copper and other metals and minerals which may be present in the water supply. This product is an excellent general purpose sequestrant which helps protect plumbing and pool walls from rust, stain and scale. It should be used for all pool openings and closings and throughout the season as needed. For initial filling of pool, if iron or other metallic contaminants are suspected, add one quart of Metal Free for each 10,000 gallons of pool water. Add Metal Free while the pool is being filled and before chlorine is added. To correct an existing colored water problem (due to the presence of minerals in the pool water), first close the pool to all swimmers. Leave the filter pump running. Stop chlorinating the pool and allow the chlorine level to drop to zero. Lower the pH of the pool water to 6.8 with pH Lower, lowering the pH will re-dissolve the metallic impurities. Add one quart of Metal Free per 10,000 gallons of water and allow the pool water to circulate overnight, or until the water is clear. Re-adjust the pH of the pool water between 7.2-7.8 with pH Rise. Begin normal chlorination and pool operation. Swimming may resume when chlorine residual is 1.0-3.0 ppm. To make up for loss of Metal Free due to backwashing and/or splash-out, add one quart of Metal Free for each 20,000 gallons of pool water, once each month.

## Questions & Answers

**Q: Is it necessary to lower the pH and chlorine every month for the maintenance doses or just for the initial dose?**
A: I never do either. If you have metal in your water just add the metal out according to your pool size. Trying to get all the chemicals just right is almost impossible. This works fine.

**Q: Product used to be tinted blue or bluish.  Now it's a clear liquid, like water.  Will this product still work as before?**
A: It worked great for us!

**Q: Can this be used on a vinyl intex pool with sand filter**
A: I don't see why not. I have a sand filter, not an intex pool, though. It didn't hurt anything, but it also didn't DO anything.

**Q: Can it be used on fiberglass pools?**
A: Yes
