Description

This product is specially designed to chelate complex minerals that naturally occur in some water supplies. Minerals, such as iron or manganese, can cause stains and discolored water. Water that has been pre-treated with this product can avoid problems that can arise from the reaction of iron or manganese with subsequent additions of chlorine or shock treatment. This product is concentrated and ready to use. This product will not interfere with chlorine, algaecides, or stabilizers. Add separately and do not mix with other chemicals. When used regularly, this product will help prevent scale build-up and mineral precipitation caused by other chemical additions. New Pools or Pool Opening: To prevent discoloration of the pool water due to trace amounts of iron, manganese, and other heavy metals, add 11/2 oz. for each 1,000 gallons of pool water. This addition should be made before any other chemicals are added. Recirculate the water, to insure uniform distribution, before proceeding with other chemical additions. Discolored Water: Have your dealer determine if the discoloration is due to iron or manganese. If the water contains less than 1 ppm of these materials, add 11/2 oz. for each 1,000 gallons of pool water. If the water contains greater than 1 ppm add proportionately greater amounts. Test the pH of the water, after addition, and adjust to 7.2-7.6, as necessary. Recirculate the water to insure uniform distribution. Scale Build Up: Scale build-up is due to high levels of calcium and other hardness minerals. Add 3/4 oz. for each 1,000 gallons of pool water and recirculate for at least 6 hours after addition. To prevent a recurrence of scale build-up, add 1-2 oz. for each 5,000 gallons of pool water each week.

  • Best product to remove metals from pool water.
Size: 1-Pack Style: Metal Out
Quality products equals beautiful pool. And this is a must have for removing metal from pool water. Stays sold out in stores. This seller has best price and fast shipping. Pool goes from muddy to clear overnight. Brush the walls and vacuum out the debris.

  • Works Just as Well as the Expensive Stuff! Works Just as Well as the Expensive Stuff!
Size: 1-Pack Style: Metal Out
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! ... show more

  • Works so much better than all the others - be certain to get Premium concentrated bottle
Size: 1-Pack Style: Premium Metal Out
Due to high levels of Iron/Manganese/Sulfur in my well water, this year I decided to try this Premium metal out. Once the pool was filled with water I added the recommended amount, ran the filter, backwashed and repeated with same dosage and about 6 hours filter time. Then I tested levels again for hardness and PH. I added calcium per my own readings. This year when I added the shock I didn't get an entire pool of chocolate milk colored water - it was a pale brownish/green hue for which I added the rest of the bottle of Premium Metal remover and ran filter overnight, backwashed in the morning and checked levels and all was crystal clear. I could now place a chlorine floater in the pool and begin my weekly doses of E-Z Pools and call it all good for the season. This Premium metal out was far better that the regular one. It worked so much faster. If you have well water, I fully recommend this product!! ... show more

  • Almost worked Almost worked
Size: 1-Pack Style: Metal Out
I have iron from well water. This product showed improvement but it’s not all gone. (The green is a reflection of trees) One bottle should treat 10,000 gallons. My pool is an above ground 3,400 gallon. I first added the appropriate amount for my size pool but saw no difference after 24 hours with the pump running nonstop. I then added the rest of the bottle, pump running continuously for the next 32 hours. The pic is the result. A definite improvement (wish I had a before pic) but not crystal clear. I’m at a loss. BTW chlorine was at 0. ... show more

  • More like "Metal In"
Size: 1-Pack Style: Metal Out
From the name you would think this separates the metal from the water, allowing it to be filtered (or so least I did). The reality is the opposite. The chemical redissolves the metal after it has been oxidized (e.g., by shock). But as soon as you bring the chlorine back up, the brown color returns. Super frustrating. It took me 2 years of frustration to realize what is actually going on and now I'm trying out a different solution to actually remove the iron. ... show more

Why did you pick this product vs others?: Does a great job clearing up brown metal filled pool water when using my well. Went from brown to clear over night Value for money: Way less money than other items and works just as good
