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.

This did not remove a rust stain and may have contributed to a major leak on one of our returns. Not worth risking using this as it does more harm than good.

The product seemed to work well, but will need additional bottles

Used a whole bottle on 7000 gallons that had metals in it, so long as you vacuum to waste the next day and backwash your filter a atleast once a day, done in two to three days.

I have very hard water and when I add chlorine to my pool it will turn a brown rusty color. I’ve had a pool for 5 years now and this stuff makes the water Crystal clear in less than 24 hours. One or 2 doses a season does the trick depending on how much additional water I have to add. I would recommend this product to anyone having this same issue. Don’t bother having your water tested. If your water turns brown after you add chlorine order this and it will clear right up. Great price, too!

Followed directions and still didn't work. Ended up upgrading to a sand filter to solve the problem. No need for more chemicals.
