Refined and Pool Stain and Metal Remover, 1-Quart

Revised Content:

This product is designed to prevent discoloration of pool water caused by iron, calcium, manganese, copper, and other metals and minerals that may be present in the water supply. As an excellent general-purpose sequestrant, it helps protect plumbing and pool walls from rust, staining, and scale buildup.

For the initial filling of a pool, if iron or other metallic contaminants are suspected, add one quart of this product for every 10,000 gallons of pool water. Introduce the product while the pool is being filled and before adding chlorine.

To address an existing colored water problem due to the presence of minerals in the pool water, first close the pool to swimmers and keep 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 using pH Lower, which will help re-dissolve the metallic impurities. Then, add one quart of this product per 10,000 gallons of water and allow the pool water to circulate overnight or until the water is clear. Readjust the pH of the pool water to between 7.2 and 7.8 using pH Rise. Resume normal chlorination and pool operation, and allow swimmers back in once the chlorine residual is between 1.0 and 3.0 ppm.

To compensate for the loss of this product due to backwashing and/or splash-out, add one quart per 20,000 gallons of pool water, once per month.

This product helps remove and prevent the buildup of calcium, cobalt, copper, iron, lead, manganese, nickel, and silver in pool water.
