Pool Metal Remover and Stain Remover, 1-Quart Spa Metal Control - Advanced Spa Metal and Stain Control & Spa Metal Prevent

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. It is an excellent general purpose sequestrant that helps protect plumbing and pool walls from rust, stain, and scale. This product should be used for all pool openings and closings, as well as throughout the season as needed.

For the initial filling of a pool, if iron or other metallic contaminants are suspected, add one quart of Metal Free for every 10,000 gallons of pool water. This should be done 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 and 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, as this will re-dissolve the metallic impurities. Then, 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. Afterwards, re-adjust the pH of the pool water to between 7.2-7.8 with pH Rise, and begin normal chlorination and pool operation. Swimming may resume when the chlorine residual is between 1.0-3.0 ppm.

To make up for the 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.

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