Pool Stain Remover for Pool Owners: 1-Quart, 4-Pack

Designed to prevent discoloration of pool water caused by various metals and minerals, such as iron, calcium, manganese, and copper, this product proves to be highly effective. Serving as a versatile sequestrant, it not only safeguards the pool's plumbing and walls against the damaging effects of rust, stains, and scale but also proves beneficial during pool openings and closings, as well as throughout the entire season whenever necessary.

For the initial filling of your pool, it is wise to employ Metal Free if the presence of iron or other metallic impurities is suspected. To achieve optimal results, add one quart of Metal Free for every 10,000 gallons of pool water while the pool is being filled, before introducing chlorine. This will help ensure the elimination of any residual metals.

To rectify an existing issue of colored pool water resulting from mineral presence, it is recommended to close the pool to swimmers. While doing so, keep the filter pump running and discontinue chlorine treatment. Allowing the chlorine level to drop to zero, proceed to reduce the pH of the pool water to 6.8 by using pH Lower. Lowering the pH facilitates the re-dissolution of any metallic impurities present. Subsequently, add one quart of Metal Free for every 10,000 gallons of water and allow the pool water to circulate overnight, or until it becomes clear. Following this, readjust the pH of the pool water to a range of 7.2-7.8 with pH Rise. Once the pool is brought back to its proper condition, normal chlorination and pool operations may resume. Swimming can be safely resumed once the chlorine residual level reaches between 1.0-3.0 ppm.

To ensure a consistent level of Metal Free in the pool water, compensate for any loss caused by factors like backwashing or splash-out. To do so, add one quart of Metal Free for every 20,000 gallons of pool water on a monthly basis.

In conclusion, this product offers a reliable solution for the prevention and removal of metals and minerals present in pool water. Its versatility, in addition to providing protection against rust, stains, and scale, makes it an ideal choice for all pool openings, closings, and regular maintenance throughout the swimming season.
