## Overview

Pool Mate 12550 Mineral Out is a powerful 1-quart treatment designed to prevent and remove stains caused by metals like iron, copper, and manganese in pools up to 10,000 gallons. Its sequestrant formula protects pool surfaces and plumbing from rust and scale, making it essential for pools using well water or metal-rich sources. Regular use ensures sparkling, clear water and long-lasting stain prevention.

## Description

Product description Pool Mate Mineral Out is especially formulated to help prevent discoloration of pool water due to iron, calcium, magnesium, copper and other minerals and metals. This product is particularly ideal for pools using well water or in regions where heavy metals are naturally present in the water. With regular use, Pool Mate Mineral Out is ideal for controlling general stains and helps maintain a sparkling clean pool. Directions Use 1 quart of this product for every 10,000 gallons of water.

Review: Used this in my hot tub on a fresh fill up to help keep the metals out of it as I am on a well and have not had any issues. I keep adding a little each week just to keep on top of it and so far so good.
Review: This product is a total game changer. I have well water with a high copper content, and every time I top off my pool, I used to worry about staining. I was using a much more expensive product from the pool company—until I found this. Pool Mate Metal Out works just as well for a fraction of the cost. It keeps my water clear and stain-free, and I’ve had zero issues with copper discoloration since switching. It’s easy to use, and a little goes a long way. If you’re looking to save money without sacrificing quality, this is absolutely the way to go. Highly recommend!
